Jan Ekström fc29620ec8 vo_gpu/d3d11: add support for configuring swap chain color space 
By default utilizes the color space of the desktop on which the
swap chain is located. If a specific value is defined, it will be
instead be utilized.

Enables configuration of the PQ color space (BT.2020 primaries,
PQ transfer function) for HDR.

Additionally, signals the swap chain color space to the renderer,
so that the render looks correct without having to specify
target-trc or target-prim manually.

Due to all of the APIs being Win10+ only, will only work starting
with Windows 10.
