Moved FSR3 classes into their own sub-namespace. This is more future-proof with an eye on porting over more FidelityFX technologies.

- Using texture arrays is now a boolean flag that can be set on dispatch, removing the need for HDRP-specific checks inside the FSR3 code and shaders.
- Debug view shader is no longer conditionally included.
- Reduced the number of multi-compile variants by removing unused keywords for each shader.
- Optimized temporary RT use; two resources can reuse the same generic intermediate temp RT.
- Reorganized some of the shader code to work nicer with the rest of the FidelityFX SDK sources.
