[Autofill] Ignore password fields in quality metrics.

Password fields aren't ever filled by the Autofill feature, so this just adds
confusion to the metrics.

FFmpeg fixups for M33 roll. Now with more Opus!

Besides the DEPs update there's also:
- Remove deprecated usage of avcodec_alloc_frame()
- Remove deprecated usage of pkt->pkt_pts
- Fix end trimming for ogg opus playbacks.
- Remove fragile bytes decoded check for end trimming.

Not all of the Opus issues are fixed yet, this just
pulls in the FFmpeg side of the fixes.  Chrome changes
are in a followup patch set.
