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.

Improve GPU storage buffer detection and memory access patterns:
- Expand NVN bias address range (0x100-0x800 vs 0x110-0x610)
- Increase alignment from 16 to 32 bytes for optimal memory access
- Raise default alignment from 8 to 16 bytes for non-biased addresses
- Refactor bias handling code for better readability
- Add detailed performance-related comments
These changes help identify more storage buffers within shaders and
ensure memory accesses are better aligned, which improves overall
shader compilation and execution performance.

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.

This commit makes two significant improvements:
1. Vulkan renderer:
- Detect and properly handle reversed depth buffers (clear_depth < 0.5)
- Force depth write enable when needed with reversed depth
- Use GREATER_OR_EQUAL comparison for reversed depth scenarios
- Fix transparency issues in games like Civilization 7 by adjusting blend factors
- Add detailed logging for depth buffer operations
2. Friend service:
- Implement previously stubbed functions including EnsureFriendListAvailable
and EnsureBlockedUserListAvailable
- Add proper event signaling to prevent games from hanging
- Implement Cancel function for improved compatibility
- Update copyright notice for the Citron project
These changes improve compatibility with modern games using reversed depth
buffers and prevent hangs in titles that rely on Friend service functionality.

Implement a robust asynchronous shader compilation system inspired by commit
1fd5fefcb1. This enhancement provides:
- True multi-threaded shader compilation with atomic status tracking
- Persistent disk caching for faster shader loading
- Command queue system for background processing
- Integration with Citron's scheduler for better resource management
- Parallel shader loading to reduce startup times
- Improved error handling and recovery mechanisms
These changes significantly reduce shader compilation stuttering and improve
overall performance when using asynchronous shaders. The implementation
maintains compatibility with Citron's existing architecture while adding
more robust threading capabilities.

This commit adds improved Vulkan functionality to the Citron emulator:
- Add thread-safe texture management with automatic error recovery
- Implement shader caching with validation support
- Add robust error handling for Vulkan operations
- Implement platform-specific initialization for Windows, Linux, and Android
These enhancements improve stability when handling texture loading errors
and provide better recovery mechanisms for Vulkan failures.

- Modify CMakeLists.txt to detect whether the host system is Windows or Linux
- Set VCPKG_HOST_TRIPLET dynamically to either "x64-windows" or "x64-linux" based on CMAKE_HOST_SYSTEM_NAME
- Previously, the host triplet was hardcoded to "x64-windows", which prevented proper building on Linux hosts

Added registration for the 'ssl:s' service using the same implementation as
the regular 'ssl' service. This fixes issues with certain titles that hang indefinitely while
waiting for this service to become available.
The issue appears in logs as:
"Server is not registered! service=ssl:s"
"Waiting for service ssl:s to become available"
This is a simple fix that reuses the existing SSL implementation instead of
creating a separate one, as both services share the same functionality.

This commit addresses critical TLB (Translation Lookaside Buffer) issues on Android by implementing several optimizations:
- Add new BufferCacheAccelerator to manage memory range overlap detection
- Implement TLB-aware memory barriers to prevent unnecessary invalidations
- Add a TLB caching system to avoid redundant flushing operations
- Create a counter to limit outstanding memory operations and prevent TLB thrashing
- Implement TLB prefetching for better memory access patterns
- Add targeted memory barriers for more precise synchronization
These changes significantly reduce the likelihood of the "0.0 FPS deadlock" issue on Android devices by maintaining a more stable TLB state and preventing cache thrashing.

The Profile-Guided Optimization configuration was previously placed at the
end of the CMakeLists.txt file, after all targets were already defined.
This was causing the PGO flags to have no effect on the build process.
This commit moves the PGO configuration to immediately after the initial
compiler flags setup and before any targets are defined, ensuring that
all targets will properly receive the PGO instrumentation or optimization
flags when those options are enabled.
This allows both CITRON_ENABLE_PGO_INSTRUMENT and CITRON_ENABLE_PGO_OPTIMIZE
to function correctly for all build targets.
