[Import Maps] Add import-maps-without-builtin-modules virtual tests

To test import maps without built-in module support.

In import-maps-without-builtin-modules virtual tests,
we skip wpt/import-maps/builtin-support/ tests because
all of them are about built-in modules, but
still run wpt/import-maps/imported/ tests because
they still contain subtests that can pass without
built-in modules/fallbacks.

+This virtual test is for testing import maps without built-in module support.
+
+In the non-virtual tests, import maps with built-in module support is tested
+because built-in modules are enabled via ExperimentalProductivityFeatures.
