Improving AggregateProcess with Geometry oriented aggregations

Description

I would like to add a new aggregation function to the Aggregate process, in particular one to aggregate the area(s) of a feature geometries.

Obviously it will work only if the aggregation attribute is a Geometry.

In practice I will add a new "SumArea" value to the AggregationFunctions enum and implement the related visitor to calculate the aggregation.

In addition optimized SQL query creation will be implemented in JDBCDataStore, through SQLDialect support on selected databases (PostGIS, SQLServer and Oracle at first).
