Introduce IME subtype switching auto mode
Create a new RotationList inside InputMethodSubtypeSwitchingController,
enabling switching in either static or recency order and either forwards
or backwards direction. Also introduce a new auto mode for IME subtype
switching, which resolves to recency order for the first switch after a
user action (reset after each switch), and to static order otherwise.
This also handles switching using the hardware keyboard shortcut
to maintain consistency.
