4406851ae7 transcriberbin: add support for speech synthesis 
This commit adds a new "synthesis-languages" property. Users can set it
to define a map of languages (typically translations) that should then
be routed through a "synthesis" bin, with its description specifiable
as the value of the map.

The output of this bin is then exposed as a new pad on the top-level
bin.

635a83a8d7 transcriberbin: notify passthrough at the appropriate time 
We want to enable passthrough internally, and only notify that
internally it has been enabled once the transcriber has been unlinked.

This way applications connected to the notify handler can synchronously
update the properties and attempt to disable passthrough again.

Doing so properly requires a refactoring of the transition to the
passthrough state, with the currently set passthrough mode maintained
separately from the target passthrough state.

This commit also finishes the work left incomplete in
17d7997137 by moving the passthrough
property to the sink pad class, making each transcriber passthrough
state independent from the others.

Also adds an example to demonstrate the behavior

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:

```

      cc-caps="closedcaption/x-cea-708, format=cc_data" sink_audio_0::language-code="es-US" \
