[Pinned Object Heap] POH perf tuning #38221

In particular we need to address the

allocation budget and
hard limit behavior.

Currently POH uses same tuning.

As was mentioned in PR review for https://github.com/dotnet/runtime/pull/34215

LOH and POH are not necessarily that similar - LOH is compacted by default for hardlimit and POH can't be compacted; LOH has in general much larger object sizes.
