refactor: push layout

[JoVictorNunes]

What does this PR do?

• 84f9eee:
  • Extracts a new component to concetrate the push layout code.
  • Renames meeting layout variable names to be more clear.
• acc55f0:
  • Doesn't allow moderators to propagate meeting layout info. Currently moderators can propagate meeting layout info, but the layout which is propagated is the presenter's, not their own. This can mislead the moderators because they think their layout is being propagated but it's not. It makes more sense to allow only presenters to propagate their layouts. (Push Layout with odd behavior #15574)

This PR seems to have broken the propagation of camera/presentation size

Thanks, @lfzawacki! I'm going to check this.

Actually there are use cases where it would make more sense for moderators to be able to push their layout - thinking of a conference or lecture, where a host or an assistant manages the BBB room and the presenter concentrates on their talk/lecture.

Couldn't agree more. We often have guests / presenters who don't have much experience with BigBlueButton. Usually moderators assist them, which wouldn't work if only presenters can push layouts.
