Adds 'lastNLimits' config value which allows to define last N value per number of participants.

Use the same moderator semantics when adding items into the remote video menu as when showing/hiding the items themselves.

This way autocomplete and keyboards work correctly.

Moves the logic from all different places into single state
listener to combine all inputs into a single output.

Adds an extra 'options' argument to the register method which
allows to use deep equality instead of a shallow one when comparing
the current and the previous selections.

Part of [1] replaces a `setPreferredVideoQuality` call with a
`setMaxReceiverVideoQuality` call. The change was part of a bigger
changeset that adds logic that tries to adjust the max based on reduced
ui turned on or off and allow to set prefered through the config.

However, by calling `setMaxReceiverVideoQuality` instead of
`setPreferredVideoQuality`, the new feature overrides the lower
resolution requested by tile-view earlier in some occasions.

This PR reverts back to using `setPreferredVideoQuality` instead of
`setMaxReceiverVideoQuality` as this achieves the same result without
overwriting the max set by the tile-view.

NOTE that this is a quick-fix and all the handling related to setting
the receive resolution will be reworked soon.

Showing the modal earlier is weird because it will be closed as soon as we
connect. Also, we don't know if we are going to be alone until we join.
