Windows/DirectX: autodetect HDR mode

[awawa-dev]

Automatic detection of the HDR signal and selection of the appropriate SDR/HDR processing path. This should remove the need to manually toggle tone mapping control in HyperHDR.

The inspiration for the package of new changes for HyperHDR ( #688 #689 ) is the new Intel N100 SBC platform and the extensive capabilities of Windows 10/11, which enable hardware-accelerated capture of even the HDR signal. You should still remember about the capturing limitations related to HDCP, e.g. when Netflix app is used, but since the video player requires its use and the user has consciously agreed to the its terms then it is not our concern. For HDCP workaround you still need a proper HDMI splitter and USB grabber.
