QUIC: Add Follow QUIC Stream support to Qt and tshark

The QUIC transport protocol provides a stream, similar to HTTP/2. Make
it possible to look at the stream contents. This can be helpful while
HTTP/3 support is not yet complete.

Known issues that will be addressed in the future:

 - If a single packet contains multiple streams, then Follow QUIC Stream
   will wrongly include data from streams other than the selected one.
   This is tracked by bug 16093 and affects HTTP/2 as well.

 - The Substream index menu does not properly filter for available
   stream numbers. If a non-existing stream is selected, then changing
   to another (potentially valid) index results in the "Capture file
   invalid." error. As workaround, clear the display filter first.

 - Follow Stream always selects Stream ID 0 instead of the first or
   currently selected stream field in a packet. Users should manually
   update the stream index as needed.
