- Consume Uniform then UAV buffer slots first.
- Don't use up a buffer slot for texel buffers as we should be using texture buffers for these now.
- If we are not using a buffer slot for the same texel slot index then don't attempt to bind the underlying SRV buffer when binding the SRV texture otherwise it'll stomp on other in use buffer slots.
- Use CountTrailingZeros64() when referencing TextureIndices as that is a 64bit type.

It is possible to use the -sandbox= option to mount an alternative file system location from which to load data. On desktop platforms, if the -sandbox= is not specified then Saved/Cooked/[Platform] is implicitly created as a sandbox. This allows runtime binaries to run off cooked data and negate the need to stage. When cooking, the Metal shader compiler creates shader libraries with files in title case. UAT will convert these into lowercase when staging. The Metal RHI is unable to load the cooked libraries as it assumes it is loading lowercase ones from staged data. This change makes sure that all shader libraries are always lowercase. Secondly, the paths to .metallib files where preprocessed in a such a way that bypassed the sandbox file system, resulting in an incorrect native path. Now the API used to convert from IPlatformFile paths to native ones is always used such that sandboxing will get taken into account.

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.
