Improve Korean keyboard support.

- Add resources for xkb:kr:kr104:kor.
- Add "Hangul" to kHotkeyNextEngineInMenu. The key works just like the Zenkaku_Hankaku key on a Japanese keyboard.
- Change Hangul-to-Hanja hotkey from "Ctrl+Alt+9" to "Ctrl+9" following Mozc's policy. Note that we can use Hangul_Hanja key for the purpose as well.

BUG=chromium-os:4812
TEST=manually checked that both Hangul and Hangul_Hanja keys are working as intended. see the bug for details.
