- 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)

Moved ZBCManager to `video_core/zbc_manager.cpp/h` for modularity. Added
`gl_zbc_clear.cpp/h` for efficient OpenGL color, depth, and stencil clears.
Updated `RasterizerOpenGL::Clear` to use ZBC with fallback. Added stencil
type validation. Fixed color mask and logging. Updated `CMakeLists.txt`.
Enhances performance and code organization.

This commit properly implements the ISBERD (Internal Stage Buffer Entry Read)
instruction that was previously stubbed. The implementation supports all
modes and shift types:
- Patch mode: Reads tessellation patch attributes using ir.GetPatch()
- Prim mode: Reads primitive attributes for geometry shaders
- Attr mode: Reads generic vertex attributes
- Default mode: Maintains backward compatibility
The implementation also supports:
- U16 and B32 shift modes for different data formats
- SKEW and O flags for advanced buffer addressing
- Proper data type conversions and bit casting
This fixes rendering issues in UE4 titles that rely on internal stage
buffer operations in tessellation and geometry shaders. The previous
stubbed implementation caused compatibility problems with modern
rendering pipelines.

Fixes: Internal stage buffer read operations in tessellation shaders
