qtdemux: Add MSE-style flush

The abort() method of SourceBuffer in Media Source Extensions is
expected to flush the demuxer and discard the current fragment,
if any. The configuration of tracks, if any, should be preserved.

qtdemux has different bahavior for flush events depending on the
context.

This patch introduces a `variant: mse-bytestream` caps setting that
allows the user to declare the data being feed to the demuxer is a MSE
ISO BMFF Bytestream, which makes use of a similar flush behavior than
adaptivedemux sources.
