f6ed40c93a qtdemux: Fix text and closed-caption handling. 
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1182
broke text and and closed caption extraction when introducing WebVTT
support, by making the output buffers not have timestamps any more.

Fix that by making the process functions copy buffer metadata
when generating new output buffers.

6cada5b064 qtdemux: Add support for wvtt (WebVTT) subtitles. 
WebVTT in ISO MP4 is specified in ISO 14496-30,
and needed for DASH support. It's stored in an
mp4 specific format. To handle it compatibly,
the wvtt boxes are converted back into WebVTT text
and pushed as application/x-subtitle-vtt

41d6f47f2b isomp4: Split buffer process functions. 
Split the different handling for closed captions, VobSub subpicture
and timed text samples into separate simplified process functions.

c47c6b4c2b isomp4: Use a function pointer for buffer splitting. 
Swap the `need_process` boolean check on qtdemux streams
for a direct function pointer to the splitting function,
so we can stop adding extra cases to the single growing
`gst_qtdemux_process_buffer()` function.
