[FLINK-11073] [state backends, tests] Activate ignored testKeyedListStateSerializerReconfiguration test in StateBackendMigrationTestBase

This test was previously ignored due to 2 missing changes:
- ListSerializerSnapshot was not respecting serializer reconfiguration
  (fixed by FLINK-11073), and
- RocksDBListState did not use the correct registered state serializer
  in backend's state meta info (fixed by FLINK-11287)

With those fixes in, the test can now be activated and expected to pass.

This closes #7434.
