* rocr: Add ProtectMemory API and use it in RemoveAccess Replace munmap + mmap with mprotect when removing memory access. This improves performance by 5-10x, ensures atomicity (no race condition window), and prepares for WSL/DXG compatibility fixes.

CPU access would fault-in system RAM instead, causing data corruption and memory leaks. Return HSA_STATUS_ERROR to fail fast rather than silently creating broken mappings. GPU-to-GPU mappings remain functional.
