Their use in the public header is deprecated and will be removed, but
they are still needed by some codecs at least as long as qscale related

9c878651db vaapi_encode: Move quality option to common code

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.

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.
