Addressed issues with EditText causing scroll
EditText methods: bringPointIntoView, and handleFocusGainInternal
trigger requestChildRectangleOnScreen in ViewPager2's internal
RecyclerView.
This can cause:
- unwanted scrolling -- e.g. when typing on some API versions
- a jump to page 0 -- EditText sometimes reports over -1M px mScrollX
This fix bypasses requestChildRectangleOnScreen calculations taking
advantage of the fact that PagerSnapHelper constraints valid scroll
values to a snapped position ones, and as a result, the problem is
reduced to choosing the correct currentItem.

Description
1) If you add multiple views as a ghosts for the same parent they would be added in the order in which they would be drown in the original hierarchy
2) They will also be drawn on top of other overlay views(not ghosts)
