We should use `common.hasIntl` in tests for test cases which are
related to ICU.
This way we can easily find the test cases that are Intl dependent.
Plus, it will be able to make the tests a little faster if we check
hasIntl first.
Also, this tweaks the log messages to unify the message.

Rather than the pseudo-wcwidth impl used currently, use the ICU
character properties database to calculate string width and
determine if a character is full width or not. This allows the
algorithm to correctly identify emoji's as full width, ensures
the algorithm will continue to fucntion properly as new unicode
codepoints are added, and it's faster.
This was originally part of a proposal to add a new unicode module,
but has been split out.
