Could you keep this file intact as this fille is generated by a script?

For now, I propose the following way.
- Move these two maps to another file
- When search modifier is enabled, remove noSearchModifierShortcuts from the
original data and add searchModifierShortcuts in keyboard_overlay.js.

Please add TODO(mazda) somewhere to improve this.

Done.
