Thanks Nyall, It was good reference for read more the new api changes in processing 
functions, finally I migrated the VectorWriter like as:

from qgis.core import QgsVectorFileWriter, QgsWkbTypes

writer = QgsVectorFileWriter(output, "System", fields, QgsWkbTypes.MultiPoint, crs, "ESRI 
Shapefile")
f = QgsFeature(...)
writer.addFeature(f)
