Epic: Pinned Object Heap tuning

[mangod9]

Tracking Epic for POH Tuning in .net 6

• Add support in GC Perf infrastructure to be able to drill into per GC data
  Added individual GC's statistics analysis feature to GC Benchmarking Infra performance#1594
• Fixing PerfView to support POH properly so that we can use it to analyze POH performance.
  Support parsing GCHeapStats_V2 microsoft/perfview#1295
  Show POH PerHeapHistoryData in Raw XML view microsoft/perfview#1379

• Fix GCPerfSim for allocating in POH
  Change NETCOREAPP5_0 to NET5_0 so that we actually allocate in POH performance#1561
• Fix GCPerfSim to allocate on POH with the right proportion ()
  Computing the allocation statistics performance#1582
  Fix the bucket weight computation performance#1704
  https://cshung.github.io/posts/poh-tuning-2/
• Experiment, understand and describe the object lifetime for objects allocated in the GCPerfSim.
  https://cshung.github.io/posts/poh-tuning-3/
• Initial experiment to compare pinning using GCHandle, and pinning using POH
• Experiment, understand and describe the performance characteristics of the GC when the survival ratio changes.
• Using POH to improve performance for static and string literals.
  Move statics to POH #47651
  Rename LargeHeapHandle* to PinnedHeapHandle* to reflect what it actually does #48371
