Check embedded windows for IME target

Browse Source 
When checking IME target, if the main window can't be IME target but the
embedded window can be, the IME will not be z ordered correctly. The IME
should be updated so it's z ordered to the embedded window. Since the
embedded window is in a different display, we set the IME target to the
host to avoid any issues with IME target being on a different display.

Test: WindowStateTests#testCanWindowWithEmbeddedDisplayBeImeTarget
Test: Host window with flag FLAG_NOT_FOCUSABLE and embedded without. IME
can be shown for the embedded window
