std: Force `Instant::now()` to be monotonic
This commit is an attempt to force `Instant::now` to be monotonic through any means possible. We tried relying on OS/hardware/clock implementations, but those seem buggy enough that we can't rely on them in practice. This commit implements the same hammer Firefox recently implemented (noted in #56612) which is to just keep whatever the lastest `Instant::now()` return value was in memory, returning that instead of the OS looks like it's moving backwards. Closes #48514 Closes #49281 cc #51648 cc #56560 Closes #56612 Closes #56940
