Introduce IME Subtype getLayoutDisplayName API
Following the existing IME Subtype getDisplayName API, this new method
will return the name of the IME Subtype's layout as specified by the IME.
When available, this will be displayed on a separate line in the IME
Switcher Menu, under the IME Subtype's display name.
