This is a groundwork for enabling LocaleSpan support in spell
checker service. TextInfo#getCharSequence is supposed to be
available in API Level 21 and later. We need some abstraction

This is a groundwork to attach LocaleSpan for committed text
in LatinIME.
This CL adds a utility method to ensure that a given range
of the text is coverted by at most one LocaleSpan. Of course
it could be possible to allow a substring to be coverted by
multiple LocaleSpans at the same time, but ensuring uniqueness
for LocaleSpan is supposed to be a good starting point.

This is a groundwork for enabling LocaleSpan support.
