fix(bbb-conf): add TasksMax=infinity to Kurento's unit files

enableMultipleKurentos TasksMax fix

 - fix issue https://github.com/bigbluebutton/bigbluebutton/issues/11358 by having the parent meeting
   tell the breakout rooms the remaining time. Currently, each room has its own countdown timer which
   could introduce drifting resulting in breakout rooms ending at different times.

fix: client may crash when loading develop version

When joining breakout audio, the output device selected in the main room is
used in breakout.
When returning from breakout rooms, the output audio device previously set in
the main room is restored.

Some specific info:
SIPSession doesn't handle Storage anymore, we do this in SIPBridge, since
it has more info about the current selected device and it doesn't depend of
a session being oppened.
We also now pass the  output device ID when joining audio sessions. We can
then keep this information in the Storage.
Closes #11663

Removed the reference for invalidateCookie, since it doesn't exist anymore.

Replace previous icon with a flexible version to fit inside other
nodes (e.g: buttons).

Implements forceRasterizeSlides (force convert presentation to png before svg) and pngWidthRasterizedSlides (force png width (px))

feat(video): set audio floor sorting as default for pagination

Set paginationSorting to VOICE_ACTIVITY_LOCAL by default (audio floors -> alphabetical -> local stream).

Rationale: a more sensible default mode for pagination that actually works a bit better for the end user than
the previous mode (presenter -> alphabetical). Should reduce the need for page switching by focusing on
the ones that are actually active in the conference.
