video_core: Add new shader format conversion pipelines

Adds several new shader-based format conversion pipelines to support additional
texture formats and operations:

- RGBA8 to BGRA8 conversion
- YUV420/RGB conversions
- BC7 to RGBA8 decompression
- ASTC HDR to RGBA16F decompression
- RGBA16F to RGBA8 conversion
- Temporal dithering
- Dynamic resolution scaling

Updates the texture cache runtime to handle these new conversion paths and adds
helper functions to check format compatibility for dithering and scaling
operations.

The changes include:
- New shader files and CMake entries
- Additional conversion pipeline setup in BlitImageHelper
- Extended format conversion logic in TextureCacheRuntime
- New format compatibility check helpers
