onvif: Rename onvif(de)pay to rtponvifmetadata(de)pay and include the metadata specifier in the other element names too
...
This is more descriptive and avoids any future conflicts with other
kinds of ONVIF specific RTP (de)payloaders.

onvifmetadata: removing encoding field
...
The encoding of ONVIF metadata is always UTF-8. ONVIF metadata may
or may not be encoded with gzip, but we don't see a use case for
transporting compressed ONVIF metadata between elements for now.

onvifaggregator: refactor, expect parsed metadata
...
The aggregator was consuming meta buffers too greedily, causing
potential interleaving starvation upstream. Refactor to consume
media and meta buffers synchronously
Also expect parsed=true metadata caps (requiring an upstream
onvifmetadataparse element).

onvifaggregator: refactor to support duration-less media buffers
...
For instance when dealing with a variable framerate media stream,
input media buffers may not hold a duration, in which case we try
to calculate one by waiting for the following buffer.

onvifaggregator: Update for minor PadTemplate API changes
...
`PadTemplate::caps()` returns a reference to the caps now instead of a
new strong reference, so keeping the template in scope as long as the
caps reference is required.
