rustdesk 3730ab0733 scrap: only apply the SDR white level to outputs DXGI reports as HDR

Review follow-up:

- An FP16 desktop is not necessarily HDR. Since Windows 11 22H2 an
  Advanced Color (WCG) SDR display is composed in FP16 scRGB too, and
  there 1.0 is the display's reference white, not 80 nits, so the
  SDRWhiteLevel scaling does not apply (Microsoft: "Reference white
  applies only to HDR displays"). Query IDXGIOutput6::GetDesc1 and treat
  the output as HDR only for DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020,
  the documented Win32 check; a non-HDR FP16 frame now gets just the
  scRGB -> sRGB transfer. Without IDXGIOutput6 (before Windows 10 1803)
  FP16 can only mean HDR.

- The SDR white level is now Option: a failed query or a reported 0 is
  "unknown" on both the initial and the refresh path, an HDR output with
  an unknown level logs a warning and keeps the 80-nit assumption until
  the periodic re-query succeeds. DISPLAYCONFIG_DEVICE_INFO_GET_SDR_WHITE_LEVEL
  needs Windows 10 1709, not 1703 as an earlier message said.
