Subject: [PATCH] [Decode] Add VC3 (DNxHD/DNxHR) decode profiles

Added two new VAProfile enums for VC3 codec support:
- VAProfileVC3HD (41): For DNxHD variants with fixed resolutions (1920x1080, 1280x720) and CIDs 1235-1259
- VAProfileVC3RI (42): For DNxHR variants supporting flexible resolutions up to 16384x16384 and CIDs 1270-1274
Included va_dec_vc3.h header to enable VC3 decode functionality in VA-API.
