Merge bitcoin/bitcoin#26118: log: Use steady clock for bench logging

Browse Source 
fabf1cdb20 Use steady clock for bench logging (MacroFake)
faed342a23 scripted-diff: Rename time symbols (MacroFake)

Pull request description:

  Instead of using `0.001` and similar constants to "convert" an int64_t to milliseconds, use the type-safe `Ticks<>` helper. Also, use steady clock instead of system clock, since the durations are used for benchmarking.

ACKs for top commit:
  fanquake:
    ACK fabf1cdb20 - validation bench output still looks sane.
