[CD Cursor] Remove displayId check from windowAcceptsTouchAt

With connected displays assumption that window's display Id should
always match with corresponding TouchState's displayId is not true. We
should rely on window's displayId to find its display.

Due to this we see hover state being unexpectedly cancelled for windows
incorrectly on windowInfo updates.

This CL
1. Removes the explicit displayId check from windowAcceptsTouchAt
2. Uses the WindowInfo to find displayId and corresponding transform to
   update hovering states when we receive a windoInfo update.
