Organize Feature: Close all To Right

So they align better with the features of the scene viewer/edit tabs, it would be a good right-click option to have, that closed all tabs to the right based on the position of the tab selected. I often need to clear a few, rather than all, scripts out to help track what I'm doing.

A Close Tabs to the Left and Close Tabs to the Right is a good idea. I'm not sure if we can enhance the default Context Menu of the TabContainer in Godot - need to be checked. If easy, we can simply add those two options there.

Hopefully so, but maybe it can be finagled into another menu if not.
