Revert "Enable av1 parser for ffmpeg."

This reverts commit 6b9bf7ba121852d20c20754c6088738dba8e4c66 since it
increases android binary size by more than 45KB, and my attempt to
reduce that increase by #ifdef'ing out the writer portions of
cbs_av1.c and cbs.[ch] did not reduce that increase enough (the
increase was still more than 26KB.
