DRILL-4120: Allow implicit columns for Avro storage format
Existing implementation of `AvroDrillTabl` does not allow dynamic columns
discovering. `AvroDrillTable.getRowType()` method returns `RelDataTypeImlp`
instance with the list of all table columns. It forces validator to check
columns from select list in `RowType` list. It makes impossible to use implicit
columns.
This fix replaces the usage of `AvroDrillTable` by `DynamicDrillTable` for
Avro format and also allows usage of non-existent columns in Avro tables to be
consistent with other storage formats.
