[GH-2095] Geopandas: Implement Scalable workaround and store as geometries
instead of EWKB (#2121)
* Implement scalable workaround by using native sedona geometries instead
of ewkb, and fixing up the tests
* Support empty_list input and use first_valid_index instead of 0 for
get_srid
* Skip ALL geopandas tests for shapely version 1 (require get_srid method)
