deps: Intl: ICU 58 bump - small icu (BIG COMMIT)

This commit contains the ICU 58.1 delta.
It is especially large because of the ICU license change,
and, because the line endings were off previously.

* bump to ICU 58.1 - check in small ICU source
* from 58.1 final http://site.icu-project.org/download/58
