(partial) Merge bitcoin/bitcoin#22707: test: refactor use of getrawmempool in functional tests for efficiency
47c48b5f35b4910fcf87caa6e37407e67d879c80 test: only use verbose for getrawmempool when necessary in functional tests (Michael Dietz)
77349713b189e80f2c140db4df50177353a1cb83 test: use getmempoolentry instead of getrawmempool in functional tests when appropriate (Michael Dietz)
86dbd54ae8a8f9c693c0ea67114bbff24a0754df test: improve mempool_updatefrom efficiency by using getmempoolentry for specific txns (Michael Dietz)

Pull request description:

  I don't think this changes the intention of the test. But it does shave ~30 seconds off the time it takes to run. From what I've seen our CI `macOS 11 native [gui] [no depends]` runs `mempool_updatefrom.py` in ~135 seconds. After this PR it should run in ~105 seconds

  I noticed this improvement should probably be made when testing performance/runtimes of https://github.com/bitcoin/bitcoin/pull/22698. But I wanted to separate this out from that PR so the affects of each is decoupled

  Edit: The major change in this PR is improving mempool_updatefrom.py's runtime as this is a very long running test. Then made the same efficiency improvements across all the functional tests as it made since to do that here
