[FLINK-5662] [table] Rework internal type handling of Table API
This PR refactors the internal type handling of the Table API. It...
- converts type to internal Row type immediately in Batch/StreamScan
- uses only Row type within the operators
- converts to target type at the very end in Batch/StreamTableEnvironment
- removes interfaces for `expectedType`
- removes the config parameter `efficient type usage`
- fixes the generic types (now `Any` means "any type" and `Row` means a
"row type")
- fixes IDE warnings and unused imports where I found them
- fixes the "Alias in front of output fails" issue
