Trust System UI owned display to receive keys

A11y service cannot get focus of bubbles because it's not a
System owned display. This patch makes System UI owned display
a trusted display. Moreover, this patch refactors the logic to
identify a trusted display by introducing FLAG_TRUSTED and
removes the trusted display check along with supportsSystemDecorations()
because the check has been included in supportsSystemDecorations().
