Fix rotary IME in Dialog window

1. FocusParkingView is used to initialize the focus. If there is no
FocusParkingView in the window, use another method (focusing the
first focusable view) to initialize the focus.
2. Don't allow to nudge out of the overlay window (e.g., a Dialog)
unless the source node is editable and the target window is an IME
window (e.g., nudging from the EditText in the Dialog to the IME
is allowed).
