Merge20230714

  1. Fix regression in pre-1809 Windows due to ExAllocatePool2.
  2. Track buffers actually used in BufferPool so that better initial preallocation choices can be made.
  3. Fix BSOD when Modules are created and memory is not available. (Fault injection/low memory situations.) Also fix associated asserts that failed in this case.
  4. Use more tags to make it easier to understand what memory is allocated. (No logical change to algorithm...just additional counters.)
  5. Add DMF_HidTarget_HidCollectionInformationGet() to HidTarget Module.

FYI building this branch gives me some warnings:

Some might have been pre-existing but I noticed today by browsing through my CI logs.
