Move RowSignature from druid-sql to druid-processing and make use of it. (#9508) 
* Move RowSignature from druid-sql to druid-processing and make use of it.

1) Moved (most of) RowSignature from sql to processing. Left behind the SQL-specific
   stuff in a RowSignatures utility class. It also picked up some new convenience
   methods along the way.
2) There were a lot of places in the code where Map<String, ValueType> was used to
   associate columns with type info. These are now all replaced with RowSignature.
3) QueryToolChest's resultArrayFields method is replaced with resultArraySignature,
   and it now provides type info.

* Fix up extensions.

* Various fixes
