Fix multiple issues in the Vulkan asynchronous presentation implementation:
- Convert regular mutexes to timed_mutex for timeout support
- Use condition_variable_any for compatibility with timed_mutex
- Fix thread synchronization with proper locking and error handling
- Add VkResultToString helper to replace missing ToString function
- Implement better error recovery with recreation attempt limits
- Add comprehensive logging for better troubleshooting
These changes make the asynchronous presentation feature more robust
and less prone to deadlocks, while keeping it disabled by default since
it may still cause instability in some games.

Implement a slider in the CPU settings tab to adjust the BASE_CLOCK_RATE
up to 1,785 MHz (Switch's official maximum clock rate). Default remains
at 1,020 MHz.
This change:
- Adds UI slider and spinbox to configure_cpu.ui with range 500-1785 MHz
- Makes BASE_CLOCK_RATE dynamic by reading from settings
- Modifies WallClock to handle dynamic clock rate changes
- Updates APM controller to properly set the clock rate
- Changes clock rate settings category from Core to CPU
The user can now easily adjust the CPU clock rate to improve performance
or manage thermals and power consumption.

When enabled, this feature allows games using present interval 0 to run with
truly unlocked FPS, matching actual hardware behavior more accurately.
Previously, Citron would cap present interval 0 at 120FPS to conserve battery,
but this prevented proper functionality of dynamic framerate mods like UltraCam
by MaxLastBreath (https://www.nxoptimizer.com/).
The setting is disabled by default to maintain the current behavior for most users.

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.

This commit adds new settings and optimizations for shader compilation:
- Add new settings:
- use_enhanced_shader_building: Enable enhanced shader compilation
- shader_compilation_priority: Control shader compilation priority
- Improve shader compilation performance:
- Optimize worker thread allocation based on CPU cores
- Add smarter async shader compilation heuristics
- Prioritize vertex and fragment shader compilation
- Add performance tracking and logging
- Add performance monitoring:
- Track shader compilation times
- Log slow shader compilations
- Monitor async shader compilation statistics
This is a work in progress commit. Further optimizations and refinements
will be needed based on testing and feedback.

Changes the default value of use_auto_stub from false to true in the settings.
This setting controls whether unimplemented functions should be automatically
stubbed during execution.
