Teresa Johnson e5cbe8fd9c [MemProf] Optionally match profiles on to manually hinted hot/cold new (#91027) ...

While we don't currently rewrite the hints on manually hot/cold hinted
allocations, enable optionally matching profiles onto those allocations
as a first step to being able to do this.

By explicitly checking whether the library function is in the list of
operator new also fixes one limitation of the prior call to isNewLikeFn.
Some operator new calls (those that specify nothrow) are considered
Malloc-like because they may return null. We want to be able to match
and rewrite these. Therefore the new test uses a nothrow variant to test
the fix for this as well.
