Subject: Disable user animations on insets whose visible frame is empty
 (refined)

Floating IME or fullscreen IME won't cause insets (except the area
overlapped with navigation bar). It doesn't make much sense to let
apps move the IME at these cases.

Fix: 157777145
Test: atest InsetsSourceConsumerTest GlobalActionsImeTest
            ImeInsetsControllerTest
