Script: Add execution timing test for no-import module script

Both Chrome and Safari agree that module scripts with no imports run
asynchronously, per the semi-ambiguous language in the HTML Standard
discussed in https://github.com/whatwg/html/issues/3746, despite the
script being "ready" immediately. Firefox seems to implement the spec
correctly, regarding the "readiness" being synchronous, however with
2/3 implementations not implementing the spec in this regard, and an
open spec issue in this area, I find it unlikely that Chromium's
will change its behavior (for compat). I'll recommend on the spec issue
that we change the spec to match Safari and Chrome, and land this test
asserting the majority behavior.
