* feat: add lockactivegroup dispatcher
The `lockactivewindow` dispatcher takes `lock`, `toggle` or `unlock` as arguments. When a group is locked, no window or group can be added to it, nor can it be added to another group, but the `moveintogroup` and `moveoutofgroup` dispatches are not affected.
Implementation details:
the lock is implement via `SGroupData.locked` flag (defaults to false).
The flag is only relevant to the group head, and upon the group head's succession, the flag will be passed down to the new head. Meanwhile, the old head's flag will be set to false.
The flag is set to false when a group is dismissed.
New condition checks have been added to the dwindle and master layout to check if target group is unlocked (and if the source is also a group and unlocked) before adding windows to the target group.

Fix two edge cases causing the dragging mouse cursor to be forced on
fullscreen windows:
- hovering over a window border and running the fullscreen dispatcher
- moving mouse focus from a monitor with the resize cursor set to a
different monitor with a fullscreen window
