Set keyboard height to 0 before show a keyboard in a different extension

Set keyboard height to 0 before show a keyboard in a different extension


This keeps the UX the same as Android.
As a side effect, it also fix issue 403789. Korea keyboard is in a
different extension and has a different keyboard height compare to US keyboard.
Before this CL, at lock screen, user see a white keyboard area that is of
korean keyboard height at first, then after US keyboard loaded, the white area
shrink to a smaller size and the US keyboard finally shows up.
After this CL, we wont see a white rectangle keyboard area and the US keyboard
only comes up after loaded.

This cl caused a regression that when the focus is not in an input field,
switching IME will force the Virtual Keyboard to show.

crbug.com/404340 is opened for the regression.
