[sanitizers][Windows] Implement __sanitizer_purge_allocator for Win64

    Windows' memory unmapping has to be explicit, there is no madvise.
Similarly, re-mapping memory has to be explicit as well. This patch
implements a basic method for remapping memory which was previously
returned to the OS on Windows.
