Revert "[vm/compiler] Use loop framework for AOT inline heuristics"

This reverts commit daae20d32e828fad298d7d12327aa30ac2927a47.

Reason for revert: 

The kernel-precomp bots are seeing this error:

../../runtime/vm/object.h: 3134: error: Handle check failed: saw 2249186640 expected Function

Not sure what that is yet, but reverting to get bots green again while I investigate.


Original change's description:
> [vm/compiler] Use loop framework for AOT inline heuristics
> 
> Rationale:
> Without proper execution counters, the inline AOT inliner
> marks every call site "cold", effectively disabling inlining
> altogether. This change introduces loop-based static heuristic
> that assumes statements nested inside loops are executed more
> frequently. This results in more inlining.
> 
> Note:
> Conservative version is used for now which yields
> more performance without increasing code size too much.
> There is still a lot of performance left at the table
> which we could exploit if we fine tune heuristics
> regarding code size.
> 
> Bug:
> https://github.com/dart-lang/sdk/issues/34473
> https://github.com/dart-lang/sdk/issues/32167
