801492b334 d3d11: Add RBGA format support 
Allocates DXGI_FORMAT_AYUV texture for RBGA so that it can be used
by video decoders.

Adding below listed formats support, and reorders supported format
list based on preference

<YUV 4:4:4>
v308, IYU2

<RGB 16bits per pixel>
RGB16, RGB15, BGR16, BGR15

<RGB 8bits per channel>
ARGB, xRGB, ABGR, xBGR, RGB, BGR

<RGB 10bits per channel>
r210, BGR10A2

<RGB 16bits per channel>

721533d042 d3d11: Use shader model 4 
Since shader model 4 is sufficient for the current pixel shader
implementations, prebuild HLSL with shader model 4 as well.

df0e6c4140 d3d11converter: Do not use R32_UINT UAV 
It does not work well with YUY2 texture on some GPUs. Always use
the same DXGI formats for each SRV and UAV

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.

c57fe82a93 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

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.
