LibJS+LibUnicode: Move replacement of number system digits to LibUnicode

Browse source 
There are a few algorithms in TR-35 that need to replace digits before
returning any results to callers. For example, when formatting time zone
offsets, a string like "GMT+12:34" must have its digits replaced with
the default numbering system for the desired locale.
