1. build: auto-load ICU data from --with-icu-default-data-dir …

   When compiled with `--with-intl=small` and
   `--with-icu-default-data-dir=PATH`, Node.js will use PATH as a
   fallback location for the ICU data.
   
   We will first perform an access check using fopen(PATH, 'r') to
   ensure that the file is readable. If it is, we'll set the
   icu_data_directory and proceed. There's a slight overhead for the
   fopen() check, but it should be barely measurable.
   
   This will be useful for Linux distribution packagers who want to
   be able to ship a minimal node binary in a container image but
   also be able to add on the full i18n support where needed. With
   this patch, it becomes possible to ship the interpreter as
   /usr/bin/node in one package for the distribution and to ship the
   data files in another package (without a strict dependency
   between the two). This means that users of the distribution will
   not need to explicitly direct Node.js to locate the ICU data. It
   also means that in environments where full internationalization is
   not required, they do not need to carry the extra content (with
   the associated storage costs).
