Post the task of disabling virtual keyboard

When show emoji/voice/handwriting vk with opt-in IME menu with virtual
keyboard disabled, the virtual keyboard will be forced shown once.
Thus, after the virtual keyboard hidden, the menu will disable the vk
to make sure it won't automatically brown. 
The menu listens on KeyboardController::OnKeyboardHidden() event to 
disable the vk, where SIGSEGV will cause.
