Update to 62.1

Changelog:
Common Changes
    Unicode 11: 684 new characters, including 7 new scripts, Mtavruli Georgian capital letters, 5 new Han characters, and 66 new emoji characters.
    CLDR 33.1:
        Unicode 11 script metadata, collation, Chinese transliteration.
        Chinese collation stroke order updated from Unicode 7 to Unicode 11 after tooling bug fixes.
    NumberFormatter
        A NumberFormatter can now be constructed from a locale-neutral skeleton string (like a DateFormat) (#8610). This is particularly useful in translated messages where placeholder details should not be translated. MessageFormat recognizes the style field as a number skeleton if it is prefixed with "::", as in "Number of files: {num, number, :: round-integer group-min2}." (#13742)
        New "conversion" functions for getting a NumberFormatter from a DecimalFormat, and a Format from a NumberFormatter.
        New C API (unicode/unumberformatter.h [permanent API docs link TBD]). (#13597) Currently it supports formatting settings only via a skeleton string.
        Several still-draft NumberFormatter methods and helper classes have been modified or renamed; the previous versions remain temporarily (as deprecated) for one release, to help with the transition.
    Break Iterator Rules: "Safe" rules are no longer required for correct break iterator operation. For back compatibility, existing rule sets containing safe rules will continue to work, with the safe rules they contain being ignored. The Break Iterator binary data format has been updated to reflect this change.
    Line Break: The boundary rules have been updated to reflect the Unicode 11 version of UAX #14. Specifically, the handling of Emoji ZWJ sequences has been improved.

ICU4C Specific Changes
    Under-the-hood overhaul of number parsing. See the design doc for a summary of changes; behavior is mostly compatible with previous versions, but there are some known differences.
    DecimalFormat now wraps the new NumberFormatter code.
