It is unclear what value this change is providing, unless there are bugs in the STL/compiler being used.

It seems odd that there is memory pressure from having this allocated while Cleanup is running.

I don't agree with the change here; either our usage of unique_ptr is flawed and should be fixed, or this is unnecessary. Adding this additional overhead isn't the right answer.

The two bug fixes made by Phil being backported into this repo by this PR are,
-fix memory leak external/msix-sdk/src/msix/PAL/Crypto/Win32/Crypto.cpp
-fix regression in inflatestream.cpp that results in unnecessary memory pressure.
