Advanced PipelineState management

[tdecroyere]

TO COMPLETE / TO Analyse

ElemAPI ElemShaderLibrary ElemCreateShaderLibraryFromShader(ElemShaderType shaderType, ElemDataContainer shaderData, shaderMetadata);
ElemAPI ElemShaderInfo ElemGetShaderInfo(ElemShaderLibrary shaderLibrary, const char* shaderName);
ElemAPI ElemShaderInfoList ElemGetShaderLibraryShaders(ElemShaderLibrary shaderLibrary);

Provide Async compile methods
Provide only one generic pipeline creation method?

Get Pipeline State Info (for compiled status etc)
ElemAPI ElemPipelineState ElemCreateComputePipelineState(ElemGraphicsDevice graphicsDevice, const ElemComputePipelineStateParameters* parameters);
Enumerate pipeline infos?

Cache functions

All options for PSO (blending etc)
Same with begin render
