Adds interceptors for Rtl(Allocate|Free|Size|ReAllocate)Heap family of functions on windows. Hooking these requires more thorough hooking of the Heap(Alloc|Free|Size|ReAlloc) family. This feature is hidden behind a CMake configuration variable since it will incur a performance penalty due to many calls to RtlValidateHeap and HeapValidate.

The tests that exercise this code are also hidden with an environment variable that will add an available feature. This is a hack since I'm not sure the best way to turn these on and off based on the cmake configuration. I am super open to suggestions on a better way to do this :)
