Rename `consume_drag_and_drop` to `mouse_target`

The functionality of the parameter is not limited to drag-and-drop
operations, but it has also other uses.
So its name should not be tied to drag-and-drop.

The API was created in the not yet released Godot 4.4-dev6, so this
change should not be considered compatibility breaking.
