Merge bitcoin/bitcoin#26024: wallet: fix sendall creates tx that fails tx-size check
cc434cbf583ec8d1b0f3aa504417231fdc81f33a wallet: fix sendall creates tx that fails tx-size check (kouloumos)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/26011
The `sendall` RPC doesn't use `CreateTransactionInternal` as the rest of
the wallet RPCs. [This has already been discussed in the original PR](https://github.com/bitcoin/bitcoin/pull/24118#issuecomment-1029462114).
By not going through that path, it never checks the transaction's weight
against the maximum tx weight for transactions we're willing to relay.
https://github.com/bitcoin/bitcoin/blob/447f50e4aed9a8b1d80e1891cda85801aeb80b4e/src/wallet/spend.cpp#L1013-L1018
This PR adds a check for tx-size as well as test coverage for that case.
_Note: It seems that the test takes a bit of time on slower machines,
I'm not sure if dropping it might be for the better._
