Expanded GIS support

Until the previous version, it supported only one coordinate system, a unitless 2D place that was not referenced to a position on earth. Now MySQL 8 has added support for a Spatial Reference System (SRS) with geo-referenced ellipsoids and 2D projections. SRS helps assign coordinates to a location and establishes relationships between sets of such coordinates. This spatial data can be managed in data dictionary storage as the ST_SPATIAL_REFERENCE_SYSTEMS table.
