b42b45af46 d3d11: Add Y412 format support
It's mapped to DXGI_FORMAT_Y416 and major format for 12bits 4:4:4
video decoding. Since DXGI_FORMAT_Y416 format cannot be a render target,
adding corresponding compute shader code too.

f52ecb9607 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.
