arc: mouse move action for input overlay

ActionMoveMouse supports simulates mouse events to touch events. The
target mouse action can be mouse hover move, and primary/secondary drag
move. The action is only effective when the mouse is locked.
Once the mouse is locked, other non-targeted mouse events will be
discarded.

Other changes in the code:
Moving some functions from input_overlay_resources_util to the
associated files where it is mainly used, The unittest is also removed
since it's basically tested by other unittest.
