MDEV-34159: Implements ST_LatFromGeoHash
The GIS function ST_LatFromGeoHash takes in input a geohash and returns its latitude. The latitude is returned as a numeric value in the interval [90, -90]. If the argument is NULL, the return value is NULL. If the argument is invalid, an ER_INCORRECT_TYPE is thrown.
