WKT serialization of 3D empty point is 2D

Description
Since GEOS 3.9, 3D empty points are serialised correctly to their 3D WKB representation.
However the WKT serialization still gives “POINT EMPTY” instead of the expected “POINT Z EMPTY. The information about the dimensionality is lost in WKT serialization.

I can confirm, following my bug reports
The geometry type is read at WKTReader::readGeometryTaggedText, but on dedicated geometry method, the Z/M extension is ignored.

This is behavior is deliberate (https://trac.osgeo.org/geos/ticket/348#comment:1) but I don't know what reasoning was behind it.

I just noticed that it is not only the empty points, but all 3D empty geometries that get serialized without the "Z".
