Update the server visibility before layout

The changes in [1] were making sure that another layout traversal takes
place, if the IME was not drawn before, but is now drawn. To address the
redundant window layout, this CL introduces `onPreLayout`, which sets
the serverVisibility. As we need the previous visibility state in the
ImeInsetsSourceProvider to reset the statsToken if needed, we store it
as well.
