And fill-in icc profile from the various window and screen capturers. Done on WindowCapturerMac, ScreenCapturerMac, WindowCapturerX11 and ScreenCapturerX11. Follow-up CLs will do it on ScreenCapturerWinDirectx and ScreenCapturerPipeWire. Useful to build the gfx::ColorSpace in chromium, especially from src/content/browser/media/capture/desktop_capture_device.cc. We do not build the color space directly here to avoid duplicating ui/gfx/icc_profile.h,cc code from chromium, which one implements icc profile caching.
