Let insets can still be controlled if its window bounds is moved

Insets source window can be moved by the display area policy so that
the window would not on the edge of the display. This makes the window
cannot provide insets to the display frame. The default animation uses
the display frame to compute insets, so the moved types cannot be
animated properly.

This CL adds an insets hint to InsetsSourceControl. It is the insets
computed from its owning window bounds. With the insets hint, the insets
animation can be played regardless of the display frame.

This CL also fixes an issue that the insets animation would be played in
the wrong direction by the fixed-rotation window.
