fmp4mux: Refactor and clean up code

parts. Overall this is functionally still the same as before.

fmp4mux: Add support for sub-fragments / chunking
...
Allow outputting sub-fragments (chunks in CMAF terms) that are shorter
than the fragment duration and don't usually start on a keyframe. By
this the buffering requirements of the element is reduced to one chunk
duration, as is the latency.
This is used for formats like low-latency / LL-HLS and DASH.

fmp4mux: add 'offset-to-zero' property
...
Add it only to 'isofmp4mux', the onvif variant already does this and
CMAF and DASH are always single-stream so you rely on inter-container
synchronization via the running-time.

fmp4mux: Handle EOS correctly if it happens before a fragment start time was determined
...
Whatever earliest time we have at that point is going to be the start
time.
Also handle the case correctly where all inputs are EOS before any
buffers were received at all.

fmp4mux: Re-work buffer dequeueing and calculations of timestamps
...
Especially simplify calculation of ONVIF UTC times. As a side-effect
this reduces the number of times the running times of a buffer are
calculated, and also causes streams to be interleaved correctly in ONVIF
mode if there is a non-constant UTC-to-running-time difference.

This can happen at the beginning of a stream if upstream is
rtpjitterbuffer and it has problems figuring out timestamps in the
beginning due to resetting / skew.
