Add Windows support to Hybrid Memory Manager

Browse source 
This commit adds Windows-specific implementation of the fault-managed memory
system, providing similar functionality to the existing Linux/Android implementation.

Key changes:
- Added Windows-specific memory management using VirtualAlloc/VirtualFree
- Implemented Windows vectored exception handler for page fault handling
- Added proper memory protection and page fault handling on Windows
- Updated memory snapshot functionality to work on Windows
- Added proper cleanup of Windows-specific resources
- Fixed type conversion issues in memory management code
- Added proper error handling for Windows memory operations
- Fixed VRAM Memory Layout Mode to allow up to 12Gb

The implementation uses Windows-specific APIs:
- VirtualAlloc/VirtualFree for memory management
- AddVectoredExceptionHandler for page fault handling
- VirtualProtect for memory protection management

This change maintains feature parity with the Linux/Android implementation
while using Windows-native APIs for better performance and reliability.
