adpcm_thp: Allow the use of extradata for the adpcm table

There are several containers that support adpcm_thp (Also known as Gamecube DSP)
streams, but only thp files contain the coeff table and previous sample inside
each frame.
Some don't even contain previous sample information at all.

This change will make it easier to implement demuxers for said containers
without having to create a new decoder.

lavfi/lut: use FF_CEIL_RSHIFT for chroma w/h rounding.
lavfi/vflip: use FF_CEIL_RSHIFT for chroma w/h rounding.
lavfi: replace passthrough_filter_frame with a flag.

With the introduction of AVFilterContext->is_disabled, we can simplify
the custom passthrough mode in filters.

This commit is technically a small compat break, but the timeline was
introduced very recently.
