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.
