Subject: Allow to obtain virtual keyboard height

On mobile platforms virtual keyboards take up significant amount of
screen space and UI containing a text box may need to be adjusted
after the keyboard appears to keep the text box visible to user. This
commit adds a way to obtain virtual keyabord height so that controls
are aware of how much they need to move.
