d3d11: Implement helper object for converter
This object will upload system memory to GPU and preprocess
texture using compute shader or software converter if needed

d3d11converter: Add support for HLSL precompile and bytecode caching
Precompile pixel shaders for simple conversion path
(without gamma/primaries conversion) in case of MSVC build.
Even if runtime compile is required (cross-compiled or complex conversion
path), do it only once and reuse the compiled bytecode.
This precompile/caching can save about 95% of time taken by
gst_d3d11_converter_new() call.

d3d11: Add support for HLSL precompile and shader caching
Compile HLSL at build time in case of MSVC, and use it if device
supports shader model 5. Also cache/reuse pixel shader and vertex
shader objects.
