Add API to get all the dependencies of a given JSScript
https://bugs.webkit.org/show_bug.cgi?id=199746

Reviewed by Saam Barati.

The method only returns the dependencies if the module was
actually evaluated. Technically, we know what the dependencies are
at the satisfy phase but for API simplicity we only provide that
information if the module graph was complete enough to at least
run.

This patch also fixes an issue where we would allow import
specifiers that didn't start "./" or "/". For reference, We have
this restriction to be consistent with the web/node. The
restriction exists in order to preserve namespace for
builtin-modules.

Lastly, this patch makes it so that we copy all scripts in the
API/tests/testapiScripts directory so they don't have to be
individually added to the xcode project.
