Also remove further references to Hull and Domain shaders as tessellation is no longer supported in UE5.

- Splitting symbol generation and shader "debug info" generation into two different cvars. This should now allow us to generate symbols post-packaging without generating different shader variants. This should also enable us to always generate symbols and still have the final deduplicated shader sizes.
- r.Shaders.Symbols is now the primary way to enable shader symbols for debugging.
- r.Shaders.GenerateSymbols can be enabled to always generate symbols without writing them to disk.
- r.Shaders.WriteSymbols can be used to force write symbols if they were previously generated.
- r.Shaders.ExtraData can be used to generate shader names for engine runtime systems to use.
- NotifyShaderCooked replaced with NotifyShaderCompiled, prep for upcoming non-cook symbol writing.
- PC DXC shader compiles should only generate debug info when requested, not all the time.
- PC FXC shader compiles should generate debug info when requested, not just when r.Shaders.Optimize is 0.

AGXRHI is starting out as a clone of MetalRHI, but will be refactored and overhauled with several goals in mind:
- Reduce/Eliminate technical debt
- Substantially improve readability and maintainability
- Introduce clear layers for platform independent vs dependent code
- Reduce memory footprint and generally improve memory usage
- Remove legacy concepts (like manual reference counting) and enable better integration with platform tools
- Implement newer and more modern features provided by Metal (such as ray tracing and enhanced command buffer debugging)
- Target/tune the software architecture and API usage for performance on Apple designed GPUs

The target info reported when running `xcrun --sdk <platform> metal -v' is always the default for the running OS, and may vary slightly between point releases. Specifying the target reduces the chances of mismatched shader version when using FASTBuild to compile shaders.
NOTE: In order for the shader version to match, the FASTBuild workers must (currently) have the same version Xcode installed, but do not necessarily need to be running the same OS version.
