Close Tabs to the Left Menu Item troch Joe D'Amore

Adds a "Close Tabs to the Left" item to the tab context menu. The menu item can also be invoked using the l access key.

Note: Due to a limitation in Firefox's web extensions API, Firefox's new "Undo Close Tabs" feature does not work as expected with this extension or any other extension which closes multiple tabs. Instead, the menu item will behave similarly to the "Undo Close Tab" button in Firefox versions prior to v78. See Bugzilla #1650956 for more information.
