vaapi_encode: Move quality option to common code

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 19388a7200e5d99c703271f05dba1c806720e808)
