[GEOT-4442] Allow SQLServer store to use native geometry serialization instead of WKB

Read SQL Server binary directly into JTS Geometries, instead of going
via WKB. While geotools will use a little longer to decode (than WKB),
SQL Server won't have to encode at all, resulting in a performance
improvement.
