- 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.
This gives more control to the application about how shaders are loaded/unloaded, and it fits in much more nicely with PPV2's resources.
Shaders are currently just serialized as part of the scene component, which isn't the optimal solution yet.
Used this to good effect to fix a few small issues that had gone unnoticed.
Also removed the Message callback which was kind of pointless, since Unity already has a well-established way of outputting warnings and errors.
