### Features
This change enables the StallDetector watchdog in Editor to submit reports to crashreporter about threads violating instrumented deadlines in the source code. This feature was available prior on Windows, and this change adds Linux support.
### Notes
New APIs:
ReportStall()
CaptureThreadPortableCallStack()
Many APIs are updated from purely "Ensure" naming to more general naming. Stalls are more like Ensures than crashes, and so the appropriate renames to make the code readable and clear have been made. In some places Ensure is replaced with the clearer: Continuable Event nomenclature.
### Testing
I synthesized an ensure on Linux, and did the same for a stall. I then compared crash report XML file to make sure they contain accurate data in the callstack, portable callstack, and other fields in the report. I also noted that the stall information was showing as expected in the crash reporter.

Also move stack to mmap'd memory instead of alloc'ing in heap
Should allow us to set & reduce size of 200k stack significantly via command line.

- 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
