Pull request description:

  Motivation
  * It seems preferable to use stdlib data structures instead of boost if they can achieve close to the same thing.
  * Code external to mempool should ideally use its public helper methods instead of accessing `mapTx` or its iterators directly.
  * Reduce the number of complex boost multi index type interactions
  * Also see #28335 for further context/motivation. This PR together with #28385 simplifies that one.

  Overview of things done in this PR:
  * Make `vTxHashes` a vector of transaction references instead of a pair of transaction hash and iterator. The trade off here is that the data is retrieved on the fly with `GetEntry` instead of being cached in `vTxHashes`.
  * Introduce `GetEntry` helper method to replace the more involved `GetIter` where applicable
  * Replace `mapTx` access with `CTxMemPool` helper methods
  * Simplify `checkChainLimits` call in `node/interfaces.cpp`
  * Make `CTxMemPoolEntry`s `lockPoints`mutable such that they can be changed with a const iterator directly instead of going through `mapTx`
  * Make `BlockAssembler`'s `inBlock` and `failedTx` sets of transaction hashes.
