feat(locale): add en_US location.county data

[matthewmayer]

replaces #1988, part of #1944

Adds en_US data to use the most common US county names from https://en.wikipedia.org/wiki/List_of_the_most_common_U.S._county_names

As there are 3,006 counties in the US its not reasonable to add them all!
