[media] uvcvideo: Add GUID for BGR 8:8:8
The Magewell XI100DUSB-HDMI[1] video capture device reports the pixel format "e436eb7d-524f-11ce-9f53-0020af0ba770". This is its GUID for BGR 8:8:8. The UVC 1.5 spec[2] only defines GUIDs for YUY2, NV12, M420 and I420. This seems to be an extension documented in the Microsoft Windows Media Format SDK[3] - or at least the Media Format SDK was the only hit that Google gave when searching for the GUID. This Media Format SDK defines this GUID as corresponding to `MEDIASUBTYPE_RGB24`. Note though, the XI100DUSB outputs BGR e.g. byte-reversed. I don't know if its the capture device in error or Microsoft mean BGR when they say RGB.
