  [CodeGen][NewPM] Preserve all MF analyses in MFPM (#124707)

Invalidation is already handled in the passes loop for MFAM, so all of
the rest analyses are preserved. (See `PassManager::run()`)

This won't change the number of invalidations, but will prevent needless
`MFAM::Invalidator::invalidate()` invocations made by results depending
on other results (since the invalidate shorts if `<AllAnalysesOn<MF>>`
is preserved)
