Merge bitcoin/bitcoin#30790: bench: Remove redundant logging benchmarks

fadbcd51fc77a3f4e877851463f3c7425fb751d2 bench: Remove redundant logging benchmarks (MarcoFalke)
fa8dd952e279a87f6027ddd2e2119bf2ae2f9943 bench: Use LogInfo instead of the deprecated alias LogPrintf (MarcoFalke)

Pull request description:

  `LogPrint*ThreadNames` is redundant with `LogWith(out)ThreadNames`,
  because they all measure toggling the thread names (and check that it
  has no effect on performance).

  Fix it by removing the redundant ones. This also allows to drop a deprecated logging alias.
