Pull request description:
Currently, `TransactionWithinChainLimit` is restricted to single-output use, and needs to be called every time for different limits. If it is replaced with a chain limit value calculator, that can be called once and reused, and is generally more flexible (see e.g. #12257).
Update: this PR now corrects usage of max ancestors / max descendants, including calculating the correct max descendant value, as advertised for the two limits.
~~This change also makes `nMaxAncestors` signed, as the replacement method will return `-1` for "not in the mempool", which is different from "0", which means "no ancestors/descendants in mempool".~~
~~This is a subset of #12257.~~
