Timothy Flynn 914675e826 LibJS+LibUnicode: Separate number formatting methods from Locale.h
Currently, we generate separate data files for locale and number format
related tables/methods, but provide public accessors for all of the data
in one Locale.h file. Rather than continuing this trend for date-time,
relative time, etc. formatting, it's a bit easier to reason about if the
public accessors are also in separate files.
