9c878651db 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.

43dab86bcd opus_pvq_search: Restore the proper use of conditional define and simplify the function name suffix handling. 
Using named define properly documents the code paths.
It also avoids passing additional numbered arguments through
multiple levels of macro templates.

The suffix handling is done by concatenation, like in
other asm functions and avoid having two separate
"cglobal" defines.

3c99523a28 opus_pvq_search: split functions into exactness and only use the exact if its faster 
This splits the asm function into exact and non-exact version. The exact
version is as fast or faster on newer CPUs (which EXTERNAL_AVX_FAST describes
well) whilst the non-exact version is faster than the exact on older CPUs.

Also fixes yasm compilation which doesn't accept !cpuflags(avx) syntax.
