Enhances the Vulkan memory allocator with better OOM handling and memory
alignment:
* Add memory recovery by cleaning up empty allocations before failing
* Implement proper fallback to non-device-local memory
* Simplify memory alignment handling for different vendors
* Add better error logging for allocation failures
* Add IsEmpty() helper to track unused allocations
* Fix alignment requirements for Adreno (4KB) vs other vendors
These changes improve the robustness of memory allocation, particularly
in low-memory situations, and streamline vendor-specific alignment
requirements.
Add workarounds for Samsung Xclipse GPUs:
- Disable extendedDynamicState3ColorBlendEquation as it is broken in Samsung
drivers, similar to AMD drivers
- Add Samsung's proprietary driver to the validated driver list for clock
boosting
- Fix log message to indicate both AMD and Samsung drivers have broken
color blend equation support
Remove stray logical OR operator from validated_driver condition.
- Added missing <thread> header for std::thread usage
- Added <fcntl.h> for O_CLOEXEC and O_NONBLOCK definitions
- Fixed struct initialization order in uffdio_copy to match declaration order

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.

Adds a new cross-platform memory management system with enhanced capabilities:
- Fault-managed memory allocation for Linux/Android platforms
- Memory snapshot and differential snapshot support
- Predictive memory reuse tracking for optimized access patterns
- Vulkan compute buffer integration
- User-configurable settings for enabling features
The system integrates with the existing Vulkan renderer to provide more
efficient memory handling, especially for compute-intensive workloads.
