IMPALA-13263: Add single-argument overload for ST_ConvexHull()
Implemented a single-argument version of ST_ConvexHull() to align with
PostGIS behavior and simplify usage across geometry types.
Testing:
Added new tests in test_geospatial_functions.py for ST_ConvexHull(),
which previously had no test coverage, to verify correctness across
supported geometry types.
