Performs better than mimalloc in cooker benchmarks, but we still default to TBB malloc until the behaviour has been explored in more depth
To opt in to mimalloc, pass -mimalloc on the command line

- Ptrdiff -> int32
- Float/int confusion and double/float
- size_t stuff; various changes to the algorithms to use a deduced IndexType template argument and/or decltype to use the appropriate size for indicies and counts
- Fixed GetNum(FString) incorrectly returning SIZE_T instead of int32, and GetNum(container) now returns whatever container.Num() does (so usually int32)

If you still need to old behavior of searching for a library we use the new PublicSystemLibraries instead (used very sparingly).
Also updated conventions on importing Android libraries to use the newly introduced Android Architecture instead, which is always set to a valid architecuture (unlike Target.Architecture for the general case)
Lastly I updated some build.cs files that were doing filesystem enumeration or copying as they were being parsed, this is highly discouraged (partially because we cache filesystem operations but also it adds a cost to something we expect to be very fast). Any operations like this should be done as part of the build if they have to be done at all.

- This allows for Confidential platforms to exist outside of the engine, and insert themselves in as needed
- Directory structure is, where .... mirrors the directory structure for Engine and projects
- /Platforms/XXX/....
- Moving to more data driven approach for ShaderPlatforms and PlatformInfo, where they can be read from DataDrivenPlatformInfo.ini files that live in the platform config folders
- Removed platform mentions from UBT, by way of changing some enums to partial classes with static members (see UnrealTargetPlatform)
- Various other UBT/UAT modifications to allow for looking in other locations for files
- THIS IS NOT A COMPLETE AND FINAL SOLUTION. WE WILL CONTINUE WORK IN DEV-BUILD BEFORE ITS READY FOR PRIMETIME
