[Expression] Add z_min and z_max functions to extract those values from a geometry

QGIS provides x_min, x_max as well as y_min and y_max functions to extract those coordinates from a geometry (particularly, lines and polygons).
It could be nice to have a way to also easily extract z min and max coordinates from geometries, without resorting to processing and aggregates expressions.
