[FLINK-6377] [table] Support map types in the Table / SQL API
This PR adds the supports of the map types in the Table / SQL API. It
covers both the parsing and the runtime.
One caveat is that users need to explicitly specify the map type. This is
because the `TypeExtractor` is unable to infer the types because of the type
erasure in Java. @StephanEwen and @twalthr can you please shed some lights on
what is the best way to approach this? Comments are appreciated.
