topology2: add ffmpeg_dec benchmark test topology

Add the ffmpeg_dec component to the host->component->host benchmark harness
so a topology instantiating the module can be built and driven (testbench or
target). Adds the per-format bench configs (generated with
bench_comp_generate.sh), registers the widget include and the ffmpeg_dec32
BENCH_CONFIG in cavs-benchmark-hda.conf, and adds ffmpeg_dec to the s32
component list in tplg-targets-bench.cmake (the filter effect path processes
S32).

Also drop the codec-setup bytes control from the ffmpeg_dec widget class so it
is a plain 1-in/1-out effect; the decoder's STREAMINFO control is added at the
instance level in a decoder topology instead.
