Merge db88db4727 into merged_master (Bitcoin PR #19339)

Changes API for AcceptToMemoryPool to no longer check maximum fee; we remove
this check from interfaces::CChain::testPeginClaimAcceptance. This is fine,
the check never should have been there (this method's job is to notice double
claim attempts and provide a more helpful message to the user; other mempool
failures should be caught later in the `claimrawpegin` logic when we call
`pwallet->commitTransaction` which actually subits to the mempool). It was
only checking fees because the API made it easier to do so than to not.
