Log:
[HEAP]
- Fix allocated/free memory fillers to match those Windows uses (winetests)
- Add missing coalesce-on-free flag check in RtlCreateHeap
- Turn on tail check/pattern filling in RtlAllocateHeap.
- Add extra stuff storage support in RtlAllocateHeap and its helpers.
- Set win32 statuses where necessary.
- Return success in RtlValidateHeap to reduce spam when running winetest.
