Implements ScaleFX algorithm for pixel art upscaling with edge
preservation. Supports both OpenGL and Vulkan with FP16/FP32
variants for hardware optimization.
ScaleFX is designed to reduce pixelation while preserving sharp
edges, ideal for low-resolution and pixel art games.

- Add TAA option to AntiAliasing enum in settings
- Implement TAA shaders for both OpenGL (GLSL) and Vulkan (SPIR-V)
- Add OpenGL TAA class with framebuffer management and temporal blending
- Add Vulkan TAA class following existing AntiAliasPass architecture
- Integrate TAA into OpenGL and Vulkan rendering pipelines
- Add UI translations and Android string resources for TAA option
- Implement Halton sequence jittering for temporal sampling
- Add motion vector validation and neighborhood clamping to reduce ghosting
- Configure aggressive temporal blending to minimize visual artifacts
- Add proper descriptor set management for Vulkan TAA implementation
The TAA implementation provides high-quality anti-aliasing by combining
information from multiple frames with per-pixel jittering, resulting
in smoother edges and reduced aliasing artifacts while maintaining
good performance and temporal stability.
Fixes: Black screen issues with proper descriptor set bindings
Fixes: Ghosting artifacts with improved temporal blending parameters
Fixes: Jitter visibility with reduced jitter intensity (50% scaling)

Frame generation was marked as WIP and not ready for production use.
This commit removes all frame generation related code and UI elements
to prevent users from enabling an incomplete feature.
Changes:
- Remove frame generation settings from Android UI (Kotlin/XML)
- Remove frame generation settings from Desktop UI (Qt/C++)
- Remove frame generation enums and settings from core (C++)
- Remove frame generation Vulkan renderer implementation
- Remove frame generation shader files
- Update CMake build configuration

Removes unnecessary d32f to bgra shader and blit functions,
update vk_texture_cache to use abgr shader for d32f to BGRA formats
updates abgr to d32f shader to comply with hardware tests
