Mark memory ranges as initialized.
The heap refers the the heap within which the region resides. This can be from nvtxMemHeapRegister, NVTX_MEM_HEAP_HANDLE_PROCESS_WIDE, or one provided from other extension API.
The regionType arg will define which type is used in regionDescArray. The most commonly used type is NVTX_MEM_TYPE_VIRTUAL_ADDRESS.
The regionCount arg is how many element are in regionDescArray and regionHandleArrayOut.
The regionHandleArrayOut arg points to an array where the tool will provide region handles. If a pointer if provided, it is expected to have regionCount elements. This pointer can be NULL if regionType is NVTX_MEM_TYPE_VIRTUAL_ADDRESS. In this case, the user can use the pointer to the virtual memory to reference the region in other related functions which accept a nvtxMemRegionRef_t.
