[FLINK-6018] Add tests for KryoSerializer restore with registered types
(This PR is a re-opened version of #3562, including @aljoscha's initial
work and my follow-up fixes. The below description is directly copied from
#3562.)
I changed `TypeSerializer.isCompatibleWith()` to
`TypeSerializer.canRestoreFrom` because the relation is not necessarily
symmetric.
I added a `KryoSerializer.canRestoreFrom()` that only allows restoring when
we previously didn't have registered types/serializers.
I added a whole bunch of tests in `StateBackendTestBase`, this should be
reviewed most thoroughly.
