Pull request description:
This PR is mostly a refactor which splits out logic used for creating wallets and for loading wallets, both of which are presently contained in `CWallet::Create()` into `CWallet::CreateNew()` and `CWallet::LoadExisting()`
The real win of this PR is that `CWallet::Create()` uses a very bad heuristic for trying to guess whether or not it is supposed to be creating a new wallet or loading an existing wallet:
370c592612/src/wallet/wallet.cpp (L2882-L2885)
This heuristic assumes that wallets with no `ScriptPubKeyMans` are being created, which sounds reasonable, but as demonstrated in #32112 and #32111, this can happen when the user tries to load a wallet file that is corrupted, both issues are fixed by this PR and any other misbehavior for wallet files which succeeded the broken heuristic's sniff test for new wallets.
It was already the case that every caller of `CWallet::Create()` knows whether it is creating a wallet or loading one, so we can avoid replacing this bad heuristic with another one, and just shift the burden to the caller.

Aside from being more legible, changing the name of `CWallet::Create()`
also validates that every instance where a new wallet is `Create()`'ed
is handled in this branch.

32023 changed AddWalletDescriptor to return util::Error, but did not
change all of the failure cases to do so. This may result in some
callers continuing when there was actually an error. Unify all of the
failure cases to use util::Error so that all callers handle
AddWalletDescriptor errors in the same way.
The encapsulated return type is changed from ScriptPubKeyMan* to
std::reference_wrapper<DescriptorScriptPubKeyMan>. This avoids having a
value that can be interpreted as a bool, and also removes the need to
constantly dynamic_cast the returned value. The only kind of
ScriptPubKeyMan that can come out of AddWalletDescriptor is a
DescriptorScriptPubKeyMan anyways.

Removed duplicate call to GetDescriptorScriptPubKeyMan and
Instead of checking linearly I have used find method so time complexity reduced significantly for GetDescriptorScriptPubKeyMan
after this fix improved performance of importdescriptor part refs https://github.com/bitcoin/bitcoin/issues/32013.
**Steps to reproduce in testnet environment**
**Input size:** 2 million address in the wallet
**Step1:** call importaddresdescriptor rpc method
observe the time it has taken.
**With the provided fix:**
Do the same steps again
observe the time it has taken.
There is a huge improvement in the performance. (previously it may take 5 to 6 seconds now it will take 1 seconds or less)
main changes i've made during this pr:
1. remove duplicate call to GetDescriptorScriptPubKeyMan method
2. And inside GetDescriptorScriptPubKeyMan method previously we checking **each address linearly** so each time it is calling HasWallet method which has aquired lock.
3. Now i've modified this logic call **find method on the map (O(logn)**) time it is taking, so only once we calling HasWallet method.
**Note:** Smaller inputs in the wallet you may not see the issue but huge wallet size it will definitely impact the performance.

Pull request description:
It is convenient to have a descriptor which specifies both receiving and change addresses in a single string. However, as discussed in https://github.com/bitcoin/bitcoin/issues/17190#issuecomment-895515768, it is not feasible to use a generic multipath specification like BIP 88 due to combinatorial blow up and that it would result in unexpected descriptors.
To resolve that problem, this PR proposes a targeted solution which allows only a single pair of 2 derivation indexes to be inserted in the place of a single derivation index. So instead of two descriptor `wpkh(xpub.../0/0/*)` and `wpkh(xpub.../0/1/*)` to represent receive and change addresses, this could be written as `wpkh(xpub.../0/<0;1>/*)`. The multipath specifier is of the form `<NUM;NUM>`. Each `NUM` can have its own hardened specifier, e.g. `<0;1h>` is valid. The multipath specifier can also only appear in one path index in the derivation path.
This results in the parser returning two descriptors. The first descriptor uses the first `NUM` in all pairs present, and the second uses the second `NUM`. In our implementation, if a multipath descriptor is not provided, a pair is still returned, but the second element is just `nullptr`.
The wallet will not output the multipath descriptors (yet). Furthermore, when a multipath descriptor is imported, it is expanded to the two descriptors and each imported on its own, with the second descriptor being implicitly for internal (change) addresses. There is no change to how the wallet stores or outputs descriptors (yet).
Note that the path specifier is different from what was proposed. It uses angle brackets and the semicolon because these are unused characters available in the character set and I wanted to avoid conflicts with characters already in use in descriptors.

Implement ReadKey and HasKey of BerkeleyROBatch, and Next of BerkeleyROCursor.
Also adds the containers for records to BerkeleyRODatabase so that
BerkeleyROBatch will be able to access the records.
LoadWallet() must only be called immediately after a CWallet is
constructed, or not at all. Doing so after any other CWallet member
functions have been called may cause pointers and other objects
setup by other those functions to become invalidated.
Since these tests and benchmarks are using completely new wallets with
mock databases, it's not necessary to call LoadWallet() anyways, so
these can be dropped.
This removes unused includes, primitives/block found manually, and the
others by iwyu:
blockfilter.h should remove these lines:
- #include <serialize.h> // lines 16-16
- #include <undo.h> // lines 18-18
In order to get records beginning with a prefix, we will need a cursor
specifically for that prefix. So add a GetPrefixCursor function and
DatabaseCursor classes for dealing with those prefixes.
Tested on each supported db engine.
1) Write two different key->value elements to db.
2) Create a new prefix cursor and walk-through every returned element,
verifying that it gets parsed properly.
3) Try to move the cursor outside the filtered range: expect failure
and flag complete=true.

The wallet tests and benchmarks both had helper functions for loading
and unloading the wallet for the test that were almost identical.
These functions are consolidated and reused.
Since we have a mockable wallet database, we don't really need to be
using BDB or SQLite's in-memory database capabilities. It doesn't really
help us to be using those as we aren't doing anything that requires one
type of db over the other, and will just prefer SQLite if it's
available.
MockableDatabase is suitable for these uses, so use
CreateMockableWalletDatabase to use that.

MockableDatabase is a WalletDatabase that allows us to interact with the
records to change them independently from the wallet, as well as
changing the return values from within the tests. This will give us
greater flexibility in testing the wallet.

Pull request description:
Instead of having database cursors be tied to a particular `DatabaseBatch` object and requiring its setup and teardown be separate functions in that batch, we can have cursors be separate RAII classes. This makes it easier to create and destroy cursors as well as having cursors that have slightly different behaviors.
Additionally, since reading data from a cursor is a tri-state, this PR changes the return value of the `Next` function (formerly `ReadAtCursor`) to return an Enum rather than the current system of 2 booleans. This greatly simplifies and unifies the code that deals with cursors as now there is no confusion as to what the function returns when there are no records left to be read.

Next()'s result is a tri-state - failed, more to go, complete. Replace
the way that this is returned with an enum with values FAIL, MORE, and
DONE rather than with two booleans.
files share the same purpose, and we shouldn't have wallet code
inside the test directory.
This later is needed to use wallet util functions in the bench
and test binaries without be forced to duplicate them.
Currently, the wallet scan progress is not saved.
If it is interrupted, it will be necessary to start from
scratch on the next load.
With this change, progress is saved every 60 seconds.

For the generic wallet tests, make DescriptorScriptPubKeyMans. There are
still some wallet tests that test legacy wallet things. Those remain
unchanged.
No change in behavior. This just moves some code from the ListCoins test
setup to a reusable util function, so it can be reused in a new test in
the next commit.
