[NFC][NewPM] Remove some AnalysisManager invalidate methods

These were misleading, they're more of a "clear" than an "invalidate".

We shouldn't be individually clearing analysis results. Either we clear
all analyses when some IR becomes invalid, or we properly go through
invalidation.

There was only one use of this, which can be simulated with
AM.invalidate(F, PA).
