  [JSC] Use modern unit/ skeleton in Intl.NumberFormat
https://bugs.webkit.org/show_bug.cgi?id=318412
rdar://181199699

Reviewed by Sosuke Suzuki.

unit/ skeleton is encouraged in the modern ICU (ICU 67~), let's use them
instead of measure-unit / per-measure-unit. Also removing type field
from MeasureUnit, as type-subtype form is no longer used and it is
kind-of deprecate status in ICU.

Also the reason of the failure in 
JSTests/microbenchmarks/intl-number-format-unit-to-parts.js
was because of this legacy format. Now it should work.
