Fix the spelling of "retrieves"

Change-Id: I33360c573a6ca7b88d0cac834caad547d66b0b2a
Switch over to getting 12-/24-hour time formats from CLDR via icu4c.

I removed the duplication in DateTimeView rather than fix that copy
of the code.

Manual fix for some Norwegian format strings.

Fixing these properly (by removing these donottranslate-cldr.xml files
completely) is blocked on icu4c, so manually fix a few strings in the
meantime.
