Support YUV 4:4:4 streaming

Add support for YUV 4:4:4 streaming

moonlight-common-c pull request: moonlight-stream/moonlight-common-c#91 merged
sunshine pull request: LizardByte/Sunshine#2533 draft

Todo, in no particular order:

• Add Vulkan headers to CI environment
  • Probably the easiest way is to add them to moonlight-qt-prebuilts submodule, collected from https://github.com/KhronosGroup/Vulkan-Headers
• Test decoding on intel (i)gpus
• Implement "YUV 4:4:4" option on settings page
  • implemented as dumb switch, no intelligent graying out
• Generate and include missing blobs of encoded video data used in decoder availability auto-detection
  • may want to revise the methodology
• Change plvk renderer heuristics to support 10-bit SDR video decoding on SDR displays, currently it tests for VK_COLOR_SPACE_HDR10_ST2084_EXT and it fails when display is not in HDR mode
  • Removed this check altogether, libplacebo might need some reconfiguration to handle tone mapping gracefully
• Investigate and possibly resolve color conversion errors
  • Full Range had issues on sunshine's side, fixed in the same 4:4:4 PR
  • Rec.601 should never be requested on third-party renderers because it has different primaries from sRGB

@cgutman I probably can't do more on moonlight side (moonlight-common-c included) without feedback. Format selection logic appears overcomplicated to me, so I've probably missed some corner cases, and you might prefer to do some things differently altogether. Also if you prefer, you can simply take this over after 5.1 is released, this may prevent the needless back-and-forth.

• switched from fork to official moonlight-common-c submodule
• rebased against 6.0 reverting library updates that got rid of vulkan/libplacebo
• added command line option for YUV 4:4:4
• extended 4:4:4 format selection logic to cover forced codecs

Hi @ns6089, this development is planned to be developed on moonlight-android?

Not anytime soon, no hardware support.
