View.setTranslationY(): queue allocate when called on CoordinatorLayout

Browse Source 
androidx adjusts the translation a little bit and immediately
reverts it to trigger a layout pass on the CoordinatorLayout.

Calling gtk_widget_queue_allocate here makes CoordinatorLayout behave
correctly, but it causes strange issues with other Views. Therefore, it is
done only for CoordinatorLayouts for now.
