Address flakiness in import-css-module-basic.html

The logs from the failures are not helpful in diagnosing the issue,
and I'm unable to reproduce any failure locally.

My best guess is that the issue is related to the test's use of 5
iframes that are injected in async_tests. There's probably some
strange timing issue that happens if things happen to load in a
particular order.

This change attempts to address the flakiness by simplifying the test.
4 of the iframes are removed and the modules are just loaded in order
at the top level instead.

The 5th test remains in an iframe because the test is supposed to
cause an error; this one is converted to promise_test.
