5ca7a7be76f2521dca895daa70949fd11df0844c rpc: Return accurate results for scanblocks (Aurèle Oulès)
Pull request description:
Implements #26322.
Adds a `filter_false_positives` mode to `scanblocks` to accurately verify results from blockfilters.
If the option is enabled, pre-results given by blockfilters will be filtered out again by checking vouts and vins of all transactions of the relevant blocks against the given descriptors.

### PR (without `filter_false_positives` mode)
Same as master
```bash
./src/bitcoin-cli -testnet -named scanblocks action=start scanobjects='["addr(tb1qcxf2gv93c26s6mqz7y6etpqdf70zmn67dualgr)"]' filter_false_positives=false

### PR (with `filter_false_positives` mode)
```bash
./src/bitcoin-cli -testnet -named scanblocks action=start scanobjects='["addr(tb1qcxf2gv93c26s6mqz7y6etpqdf70zmn67dualgr)"]' filter_false_positives=true
{
"from_height": 0,
"to_height": 2376058,
"relevant_blocks": [
"0000000000000082f7af3835da8b6146b0bfb243b8842f09c495fa1e74d454ed",

]
}
```
Also adds a test to check that the blockhash of a transaction will be included in the `relevant_blocks` whether the `filter_false_positives` mode is enabled or not.
