Add GetMaxResolutionForVAConfigID function to get hardware supported maximum
resolution for video encode and decode. This is also the preparation of
removing --ignore-resolution-limits-for-accelerated-video-decode flag.
Because this function uses va_config_id as parameter, we refactor
vaapi_wrapper and add LazyInstance to initialize supported profile
infos once and reuse it in Initialize and GetSupportedEncodeProfiles
functions.

BUG=350197
TEST=Test on squawks, and lumpy. Make sure this function works well.
