Add a workaround for crbug.com/139556.
* Switch to the next IME when Shift+Alt+Enter (or Space) are pressed and then Enter (or Space) is released. Since most of CJK IMEs use either Enter or Space as a "commit" key, this should work fine for such IME users.
* The workaround might not be good enough for Cangjie/Quick IME users since the IME also uses [0-9] keys for committing a string.
We might have to add additional workaround for switching from a keyboard layout to an IME, but I believe this CL would be a good enough as an initial trial.
BUG=139556
