Uniform Buffer layout name

more debug info for this and other bugs: OR-7159 CRASH: Client crashed at start of match in D3D11Commands.cpp
Adding OptionalData (key value pairs) to the shaders (to put shader name into the shader code for better debugging), affects all RHI, invalidate DDC key for all shaders, cleanup existing code (was adding 0/1/5 bytes and had to compensate in many areas)
OptionalData:
key is a char, value is up to 255 bytes, up to 64K in total

- With 'r.UseAsyncShaderPrecompilation' enabled shader precompilation is now executed on the render thread alongside the predraw, not as a single operation on loading the binary cache.
- The setting 'r.TargetPrecompileFrameTime' controls what the target frame rate should be when performing async. precompile and the shader cache will try and adjust how many shaders to precompile to stay within this limit, with a minimum of 1 shader per frame.
- The shader cache is now updated during initial loading to take advantage of the time spent loading essential data to do as much of the precompile as possible.
- It is possible to accelerate the shader cache's precompilation by specifying 'r.AccelPredrawBatchTime' and 'r.AccelTargetPrecompileFrameTime' to larger values, then calling FShaderCache::BeginAcceleratedBatching() to start using the more aggressive values and FShaderCache::EndAcceleratedBatching() to go back to the normal values.
- Calling FShaderCache::FlushOutstandingBatches() will force completion of all outstanding batched precompilation and predraws during the next frame.

Optionnal outputs are : CustomData, PreshadowFactors and Velocity (when enabled)
Controlled by ini file variable : r.SelectiveBasePassOutputs=true

RHi now provides CreateAndLock functions for Vertex and Index buffers which are more efficient on certain platforms.
Use r.PS4StandardWriteLocks=1 to enable the old default functionality for testing if necessary.

Fix for FShader crash while streaming a level.
- Made FShader ref counting more thread safe
- Added extra locks when unregistering the shader so that released shaders can't be found in the shader id map while a shader is being released
- Made sure FShaderType::FindShaderById adds a reference to existing shaders while serializaing inline shader maps.
