[RTL/NTOSKRNL]

- Seperate some usermode only heap functions into their own file and implement dummys in the kernel rtl so that they don't get included in the kernel
- Convert usage of RTL_CRITICAL_SECTION in heappage.c to use of HEAP_LOCK
- Implement A kernel dummy for RtlCallVectoredExceptionHandlers, so we don't put vectored exception handler code into ntoskrnl
- Now we don't have critical section code in the kernel anymore, which wasn't working anyway.
