Increase FRAME_BUFFERS to 16.

Increase FRAME_BUFFERS to 16, one greater than the old value (15).

This reverts the following change in commit
64e4cba53b6ecd6ca72aa0300246d614c97045ee
(https://aomedia-review.googlesource.com/c/aom/+/69001):

    Reduce FRAME_BUFFERS by 3. This is the counterpart of
    https://chromium-review.googlesource.com/c/webm/libvpx/+/560620.

That change is wrong for libaom because the cpi->scaled_ref_idx array in
libaom has a bigger size (8 vs. 4).

The last element in the cpi->scaled_ref_idx array is unused. So the
frame buffer pool needs a total of REF_FRAMES + 1 + 7 frame buffers.

Also remove an old TODO(jkoleszar) comment.
