vaapi_encode: Move quality option to common code

Browse Source 
Use AVCodecContext.compression_level rather than a private option,
replacing the H.264-specific quality option (which stays only for
compatibility).

This now works with the H.265 encoder in the i965 driver, as well as
the existing cases with the H.264 encoder.

(cherry picked from commit 19388a7200)
