Currently if a button in the main toolbar is not visible, the button is
not replaced by another button from the overflow menu.

As part of the PR, it also fixes:
 - Removes button aliases
 - Unifies the keys in the object returned by getAllToolboxButtons and the button keys
 - Makes sure that the number of buttons displayed are always the same as the number of buttons specified in the thresholds and removes the exception for not filling up the main toolbar with buttons from overflow menu when reactions button is disabled.
 - Introduces a priority for buttons that will be used to fill empty spaces in the main toolbar.

Fixes the issue with adding duplicate elements in buttonsWithNotifyClick and participantMenuButtonsWithNotifyClick with custom buttons.

Filters the toolbarButtons in redux depending on the visitor state instead of filtering them every time in mapStateToProps. This will prevent unnecessary rerenders of the toolbar.

Additionally:
 - Moves visitor buttons const from features/config in features/toolbox.
 - Removes dublicate functions isButtonEnabled and isToolbarButtonEnabled.
 - Adds more buttons to the visitor allowed buttons which functionality has been any way accessible trough shortcuts or somewhere else.
 - Enables customButtons to be visible for visitors.

The previous version of getToolbarButtons function was actually adding the custom buttons on every call to the config toolbarButtons array, effectively creating dublicates of every custom button. The PR fixes this issue.

Also now we will be running the getToolbarButtons calculation only when needed.

Move visible logic inside each button
Move click functionality inside each button
Extract getButtons function from Toolbox components to functions file

Also, ignore the toggle screenshare shortcut when the video sender limit is reached.

This fixes an issue where the user muted by focus is able to unmute themselves even when the sender limit has been reached.

* feat(conference) Impl audio/video mute disable when sender limit is reached.
Jicofo sends a presence when the audio/video sender limit is reached in the conference. The client can then proceed to disable the audio and video mute buttons when this occurs.

* squash: use a different action type and show notification.

Create standalone components for each feature and move all state to them.
Toolbars are now dummy containers.

This PR takes The Bulldozer Approach (R): removes the old toolbox and lots of
associated code, though not all of it. Subsequent cleanups will follow.
