The old code cleared ICU library internal state between test runs, but
not the icu_util internal state.  This caused the new ICU configurations
never to be loaded, since the default behavior of the loader is to make
loads lazy and idempotent.

Clearing the internal state of icu_util enabled loading new
ICU data in each individual test case.

This initialization issue may have contributed to arm64 test failures
that mysteriously came and went a few days back, possibly related to
test run ordering.
