[CD Cursor] Apply selection logic to change cursor displayId

In connected displays scenario, this tracks the latest display the
cursor is at, within the DisplayTopology. By default, this will be set
to topology primary display, and updated when mouse crossed to another
display.

Note: If associatedDisplay is in different topology, mouse will simply
be on the associatedDisplay, keeping existing behavior
