✨ Create a new window of an open workspace

### Description

Users should be able to create a new window of an already open workspace.

This will create a duplicate of the workspace and will start off at the exact state of the focused workspace. This means all of the editor tabs open, editor layout, navigator/inspector/utility active tab and open state will all be the same in the duplicated workspace.

These things however will not be synced so any changes to the UI state on one window, will not be reflected in the other.

There will need to be some things that are synced though like actively running processes and open terminals.

The following should be added in support of this feature:
- **Menu item:** File → New → Window
- **Keyboard shortcut:** ⇧ ⌘ T
