Nyall Dawson 767cb12c2a Add QgsMemoryProviderUtils.createMemoryLayer for easy creation
of new memory layers from QgsFields/QgsCoordinateReferenceSystem/etc

Since memory provider cannot use QgsVectorLayerImport we need
another centeralized function for creating new memory layers
without the need to manually create the uri string.
