Optimize address translation and write tracking on the MMU (#571)
* Implement faster address translation and write tracking on the MMU
* Rename MemoryAlloc to MemoryManagement, and other nits
* Support multi-level page tables
* Fix typo
* Reword comment a bit
* Support scalar vector loads/stores on the memory fast path, and minor fixes
* Add missing cast
* Alignment
* Fix VirtualFree function signature
* Change MemoryProtection enum to uint aswell for consistency
