Original commit message:
  Fix default Intl language tag handling

  With certain ICU data bundles (such as the Node.js "small-icu"),
  %GetDefaultICULocale() may return a more specific language tag (e.g.
  "en-US") than what's available (e.g. "en"). In those cases, consider the
  more specific language tag supported.

  This CL also resolves the following Node.js issue:
     nodejs#15223

Refactor code such as using template literals, and also make sure
uncaughtException listner is detached after firing once to avoid

listner.

Currently when building --without-ssl a 'ERR_NO_CRYPTO' error is
reported.

This is not currently being picked up by the crypto-check lint rule as
it does not actually require any crypto modules directly, but instead
this is done by common/benchmark.

When building the node with `--shared` option, the major output is the
shared library. However, we still build a node executable which links
to the shared lib. It's for testing purpose. When testing with the
executable, some test cases move/copy the executable, change the
relative path to the shared library and fail. Using lib path env would
solve the issue. However, in macOS, need to change the install name for
the shared library and use rpath in the executable. In AIX, `-brtl`
linker option rebinds the symbols in the executable and addon modules
could use them.
