Readbacks are executed via FRHIGPUBufferReadback. FComputeGraphTaskWorker creates the readbacks and polls active readbacks each frame.

- Add option for ShaderType to declare which FShaderBindingLayout needs to be used for shader gen and runtime binding
- Add helper function to generate FShaderBindingLayoutContainer from array of uniform buffers and EShaderResourceTableFlags (only supports bindless mode right now)
- Serialize the FRHIShaderBindingLayout in FShaderCompilerEnvironment so it can be used by the shader compiler backends
- FShaderBindingLayout can add required symbols to the FShaderCompilerInput which shouldn't be dead code eliminated (required for Shader resource table building)
- Serialize the hash of RHIShaderResourceTable in the platform specific shader binary data so it can be used during runtime RTPSO validation (all shaders in the RTPSO need the same RHIShaderResourceTable)
- Renamed pRootSignaure member to RootSignature (style guide)

EShaderPermutationPrecacheRequest is returned to define if a permutation is required, not required or development only. Only required PSOs are precached.
DevelopmentOnly should be used for debug permutations and won't trigger an ensure when permutation is used at runtime which isn't requested for precaching.
Validation also runs in editor builds.

[shaders]
- store shadertype associations for each shader in a shadermap in the editor only data
- output a debug artifact containing per-shadertype permutation/memory stats; note that this is not directly representative of final shader memory usage since it doesn't account for shader library deduplication or shader library chunk re-duplication; it is only intended to be used as a tool for tracking/identifying shader growth due to added/modified shadertypes
- remove the old "dumpshadercodestats" path from the shader library, as well as the stats tracking "unique" shaders and shader memory; the former is no longer used and the latter does not correctly account for library chunking
- bump shader version due to shadermap editoronly data change

Also changed use of RemoveAtSwap() to RemoveAt() so that ordering of enqueued items is respected when executing.

Remove "r.RecompileRenderer", STORE_ONLY_ACTIVE_SHADERMAPS, and all associated dead code paths that are no longer used.
- r.RecompileRenderer has been broken since at least August 2019 when CL 8231930 disabled the implementation of BackupGlobalShaderMap etc
- STORE_ONLY_ACTIVE_SHADERMAPS was disabled in 14363137 (September 2020) to resolve FORT-312158 (enabling the new loader). Fortnite was the only user of this code path.
- This is a delete-only change.

* TRACE_CPUPROFILER_EVENT_SCOPE(ScopeName) --> to be used with a plain text as scope name (not a string!). If the parameter is a string ("abc" or TEXT("abc")), the quotes (and the TEXT prefix) will be included in the actual timer name.
* TRACE_CPUPROFILER_EVENT_SCOPE_STR("scope name") --> to be used with a static string (const ANSICHAR* or const TCHAR*); ex: when the scope name needs to include a space char
* TRACE_CPUPROFILER_EVENT_SCOPE_TEXT(*MyScopeName) --> to be used with a dynamic string (const ANSICHAR* or const TCHAR*)
