[Fiber] Move Profiler onPostCommit processing of passive effect durations to plain passive effect (#30966)

We used to queue a separate third passive phase to invoke onPostCommit
but this is unnecessary. We can just treat it as a plain passive effect.
This means it is interleaved with other passive effects but we only need
to know the duration of the things below us which is already done at
this point.

I also extracted the user space call to onPostCommit into
ReactCommitEffects. Same as onCommit. It's now covered by
runWithFiberInDEV and catches.
