1488315d76ee40b9d021b7d0ecd01207eee4a426 policy: Allow any transaction version with < minrelay (Greg Sanders)
Pull request description:
Prior to cluster mempool, a policy was in place that
disallowed non-TRUC transactions from being
TX_RECONSIDERABLE in a package setting if it was below
minrelay. This was meant to simplify reasoning about mempool
trimming requirements with non-trivial transaction
topologies in the mempool. This is no longer a concern
post-cluster mempool, so this is relaxed.
In effect, this makes 0-value parent transactions relayable
through the network without the TRUC restrictions and
thus the anti-pinning protections.

With a total ordering on mempool transactions, we are now able to calculate a
transaction's mining score at all times. Use this to improve the RBF logic:
- we no longer enforce a "no new unconfirmed parents" rule
- we now require that the mempool's feerate diagram must improve in order
to accept a replacement
- the topology restrictions for conflicts in the package rbf setting have been
eliminated
Revert the temporary change to mempool_ephemeral_dust.py that were previously
made due to RBF validation checks being reordered.

In the functional tests there are lots of cases where we assert != which
this new util will replace, we also are adding the imports and the new assertion
The weight unit is merely a consensus rule detail and is largely
irrelevant for fee-rate calculations and mempool policy rules (e.g. for
package relay and TRUC limits), so there doesn't seem to be any value of
using a granularity that we can't even guarantee to reach exactly
anyway.
Switch to the more natural unit of vsize instead, which simplifies both
the padding implementation and the current tests that take use of this
padding. The rather annoying multiplications by `WITNESS_SCALE_FACTOR`
can then be removed and weird-looking magic numbers like `4004` can be
replaced by numbers that are more connected to actual policy limit
constants from the codebase, e.g. `1001` for exceeding
`TRUC_CHILD_MAX_VSIZE` by one.

Pull request description:
This pull request enables full rbf (mempool policy) by default. #28132 was closed recently with this [comment](https://github.com/bitcoin/bitcoin/pull/28132#issuecomment-2225369634).
---
Rationale:
- Full RBF config option was added in July 2022: https://github.com/bitcoin/bitcoin/pull/25353
- It is used regularly: https://mempool.space/rbf#fullrbf
- Most mining pools are using it: https://github.com/bitcoin/bitcoin/pull/28132#issuecomment-2059120917

Keep mentions of v3 in debug strings to help people who might not know
that TRUC is applied when version=3.
Also keep variable names in tests, as it is less verbose to keep v3 and v2.
