79657e5671 transcriberbin: fix inspect with missing elements 
Relax the dependency on `awstranscriber` by still building the initial
state when it is absent, this also means an alternative transcriber can
be linked even when `awstranscriber` was not available during
construction.

Also fix property getter / setters to avoid unwrapping the pad state,
and bubble up channel bin construction errors instead of unwrapping (eg
when textwrap was not available).

f0df6874d8 transcriberbin: fix property proxying 
As part of https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/merge_requests/1546
the element started implementing the GstChildProxy interface in order to
expose properties on its sink pads, but the implementation was
incorrect and broke proxying to children elements.

In addition, an intermediary bin was introduced with no name, making it
hard to set the properties of the inner elements through the child
proxy interface, it is now named according to the name of the pad it
corresponds to.

Finally, the default transcriber is back to being named "transcriber".

17d7997137 transcriberbin: add support for consuming secondary audio streams 
In some situations, a translated alternate audio stream for a content
might be available.

Instead of going through transcription and translation of the original
audio stream, it may be preferrable for accuracy purposes to simply
transcribe the secondary audio stream.

This MR adds support for doing just that:

* Secondary audio sink pads can be requested as "sink_audio_%u"

* Sometimes audio source pads are added at that point to pass through
  the audio, as "src_audio_%u"

* The main transcription bin now contains per-input stream transcription
  bins. Those can be individually controlled through properties on the
  sink pads, for instance translation-languages can be dynamically set
  per audio stream

* Some properties that originally existed on the main element still
  remain, but are now simply mapped to the always audio sink pad

* Releasing of secondary sink pads is nominally implemented, but not
  tested in states other than NULL

An example launch line for this would be:

```
$ gst-launch-1.0 transcriberbin name=transcriberbin latency=8000 accumulate-time=0 \
      cc-caps="closedcaption/x-cea-708, format=cc_data" sink_audio_0::language-code="es-US" \
      sink_audio_0::translation-languages="languages, transcript=cc3"

* When building from a non wildcard-named template, the name of the template is
  automatically assigned to the Pad. User can override with a specific name by
  calling `name()` on the `PadBuilder`.
* When building with a target and no name was provided via the above, the
  GhostPad is named after the target.

c0dc6eb35c cea608utils: track last channel for characters without channel embedded 
If a basicna character is received, it will always have a channel of 0
even if it's directed at a different data channel.  Fix by keeping track
of the last channel from other commands and using that when producing
text in the basicna subset.

8cb328b6f2 transcriberbin: add support for translations 
With this, if the transcriber element in use supports "translation_src_"
request source pads, the user can now specify what languages to
translate to and how to map them to 608 channels (only CC1 and CC3 are
supported).

For instance, translation-languages="languages, CC3=transcript, CC1=fr"
will cause the original transcript to be muxed into the CC3 channel, and
the French translation to be muxed into the CC1 channel.

93f61483b5 tttocea608: fix disappearing text after special character in non-popon 
To avoid special characters getting de-duplicated by the decoder, we
insert no-op control commands after those. The no-op command must be
picked according to the mode we're in however, inserting
"resume_caption_loading" commands in roll-up mode caused obvious issues.

new caps seems cleaner)

9e3110988c transcriberbin: fix initial transcription bin setup 
When passthrough=false at construction and the transcription bin
is linked after receiving video caps (and not on state change),
there could be a race where transcription-bin was linked with
tee but state change of the transcription-bin was not finished.

If upstream pushed a buffer at that point, it got a flushing flow
return and stopped streaming.

This is the same issue and the same fix as 558656deb5
for the initial passthrough=false case.
