Re: [PATCH v2 0/1] MR6791: msvcrt: Do not create in newer msvcrt versions a separate heap. (ASan)

[Bernhard Übelacker (＠bernhardu)]

v2:
- Fixed #if condition in msvcrt_destroy_heap.
- Use `_get_heap_handle` instead of the indirect detection via `HeapValidate(GetProcessHeap(), ...)`

For convenience this are the links into llvm-project, where this `HeapValidate(GetProcessHeap(), ...)` is called:
[IsSystemHeapAddress](https://github.com/llvm/llvm-project/blob/71f82bba35c48eaf98c50aeeb4d2675156...) and [Deallocate](https://github.com/llvm/llvm-project/blob/6ce44266fc2d06dfcbefd8146279473cca...).
