[Launcher3] Hide keyboard when fastscroller scrolling down and keyboard

Browse Source 
shown

Implement keyboard hiding logic: Hide keyboard when scrolling down (y > mLastY) unless already requested (mRequestedHideKeyboard). Track hide request state to prevent redundant calls.

New added logic: Only hide keyobard while dragging the scrollbar
