- This will make maintenance for multiple platforms a lot easier (i.e. just preflight)
- Will be easy to get callstack and debug since it will be compiled on the machine it is debugged on
- Easier to try out modifications on mimalloc itself
- Fix mimalloc compilation under Clang 10
- Fix mimalloc inconsistent usage of MI_ENCODE_FREELIST define
- Fix mimalloc inconsistent usage of _WIN32 define
- Implement MacOS and Unix -mimalloc command-line switch
- Some MacOS changes were contributed by Will.Damon

- When CRC runs out of process, instead of reading the current thread context of the crashed thread, read and use the crash context that was reported during the crash (which is different).
- Added an optional context parameter to FGenericPlatformStackWalk::CaptureThreadStackBackTrace(), implemented it across all platforms, but only used on Windows.
On Windows, fixed InitStackWalking() and InitStackWalkingForProcess() to reset the process that needs to be walked.
- CRC, running out of process may run its own process or the Editor process and which ever was walking first ruled out the other.

Unix-related files are in the changelist because FUnixPlatformStackWalk overrides StackWalkAndDump[Ex]. The compiler won't pick up the overload in FGenericPlatformStackWalk, hence the need to forward for Unix. Coincidentally, the old versions use the context to condition backtraces by program counter. That we can skip out on for these new overloads.
