Terminal Tabs Closing Wrong Tab, Terminal Right Click Semantics

[thecoolwinter]

Description

• Fixes a bug where the wrong terminal tab would be removed when deleting a tab.
• Updates the right-click menu to show "Kill Terminals" when the action would kill multiple terminals. Also updates the tab list to work as expected (right clicking an element of a large selection performs the action on the entire selection, otherwise, just the item that was clicked).
• Fixes an issue where the utility area was covered in the accessibility inspector.
• Wrote tests for the utility area view model.
