Replace derived CriteriaQuery with String-based queries.
Introduce new DSL to construct JPQL queries. Refactor ParameterMetadata to PartTreeParameterBinding. Disable Keyset pagination with projections for Eclipselink as Eclipselink doesn't consider type hints for JPQL queries. Closes #3588 Original pull request: #3653
