[windows] Fix deadlock on mmap failure due to CHECK recursion
Summary:
Printing a stacktrace acquires a spinlock, and the sanitizer spinlocks
aren't re-entrant. Avoid the problem by reusing the logic we already
have on Posix.
This failure mode is already exercised by the existing mmap_limit_mb.cc
test case. It will be enabled in a forthcoming change, so I didn't add
standalone tests for this change.
