feat: Add frame generation and enhance UE4 game compatibility

- Add frame generation settings (enabled/disabled, interpolation/extrapolation modes) - Add frame skipping settings (enabled/disabled, adaptive/fixed modes) - Implement frame skipping logic with adaptive and fixed modes - Enhance UE4 crash handling with recovery mechanisms - Add support for signed and float 32-bit image formats across shader backends - Update Vulkan Validation Layers to v1.4.321.0 - Fix duplicate frame skipping options in Qt UI - Improve memory handling for UE4 games (Hogwarts Legacy compatibility) - Add enhanced bindless texture handling with fallback approach - Update Android build configuration and dependencies Signed-off-by: Zephyron <zephyron@citron-emu.org>
