avcodec/audiotoolboxenc: remove CAP_VARIABLE_FRAME_SIZE from alac
AV_CODEC_CAP_VARIABLE_FRAME_SIZE has been set for alac_at encoder,
which means avctx->frame_size should be zero. However, alac_at
encoder also set avctx->frame_size. This leading to assert failure
in ffmpeg_sched.c
av_assert0(enc->sq_idx[0] >= 0);
Actually, the implementation of audiotoolboxenc.c doesn't support
frame_size been zero.
Fix #10720.
