[BEAM-2740] introduce the new InnerBeamSqlEnv/BeamSqlEnv
Summary:
* Simplified `BeamSqlEnv`: now you can only register UDF/UDAF in
`BeamSqlEnv`, and `BeamSqlEnv` just record the udfName -> udfClass mapping,
actually work will be done by `InnerBeamSqlEnv`.
* `BeamSqlEnv` is only used by the surface API classes.
* `InnerBeamSqlEnv` is actually the old `BeamSqlEnv`, it holds schema and
planner.
* `InnerBeamSqlEnv` is only used by the implementation classes.
* `BeamSqlEnv` is converted to `InnerBeamSqlEnv` automatically in `BeamSql`
and `BeamSqlCli`.
* `BeamSqlEnv` and `InnerBeamSqlEnv` are quite different, so can not share
the same interface.
