Expression builder : add layer_property(...,'distance_units') 
To complete the existing function layer_property(...), this change add a new argument 'distance_units' for return a string with the layer distance units (see QgsUnitTypes::DistanceUnit)

This function can be used for display units for labels, in layouts or for access to more layer properties in the expression builder for algorithms.
