Changed ShaderArchive, GlobalShaderCache, ShaderDebugInfo and Autogen to use ShaderPlatformName and not ShaderFormat when naming their output files.

- Saves disk size and runtime memory on all platforms that use IoStore-based shader archive (on some - significantly).
- Decompression time is small and seems to get lost in noise given how rarely shaders are actually created.
- Also changed IoStore-based archive to allocate preload entries on demand, and disabled preloading singular shaders (used by the PSO cache) as the API needs more work.

- Produces an image in Saved/Profiling with the preloaded and created shaders, helping to understand preloading / creation patterns.
- Only works on desktop platforms in Development. Disabled by default (set r.ShaderCodeLibrary.VisualizeShaderUsage=1 in ini to enable).

- Provides about 8% runtime memory savings (in local tests).
- Also, adds more compression types for shaders.
- Impact on the shader compilation (in SCWs) seems to be negligible in local tests.

- Disable RDG parallel execution on D3D11.
- Precreate ClearReplacement shaders
- Also add a check to catch other possible issues before it's too late.

FPreloadShaderTask takes the ShaderPreloadLock in FShaderCodeArchive::OnShaderPreloadFinished() and then issues an async read. Another task can be picked up by the thread while waiting on that read. If that new task is also a FPreloadShaderTask it will try to aquire the ShaderPreloadLock again and deadlock.
Introduce an EnsureReadNonBlocking method to IMemoryReadStream which can be called outside the lock to ensure the data is ready. We can then lock and copy out the data without incuring a wait and the potential for another FPreloadShaderTask being run while we hold the lock.
