This commit imports mimalloc's source code as per v2.0.9, fetched from the tag at https://github.com/microsoft/mimalloc. The .c files are from the src/ subdirectory, and the .h files from the include/ subdirectory. We will subsequently modify the source code to accommodate building within Git's context. Since we plan on using the `mi_*()` family of functions, we skip the C++-specific source code, some POSIX compliant functions to interact with mimalloc, and the code that wants to support auto-magic overriding of the `malloc()` function (mimalloc-new-delete.h, alloc-posix.c, mimalloc-override.h, alloc-override.c, alloc-override-osx.c, alloc-override-win.c and static.c). To appease the `check-whitespace` job of Git's Continuous Integration, this commit was washed one time via `git rebase --whitespace=fix`.
