avcodec: remove deprecated FF_MAX_B_FRAMES compat define

FF_MAX_B_FRAMES was removed from FFmpeg headers as there is no longer
a global libavcodec-wide limit on B-frames. Remove the compat define
from avcommon_compat.h and drop the arbitrary upper bound clamp in
encoder.c, letting libavcodec's per-encoder validation handle limits.
