QQmlPropertyMap: Add a method to insert multiple values at once
This avoid re-building the metaobject for every property added. As
rebuilding the metaobject is an effort linear in the number of
properties, the runtime when adding multiple properties via singular
insert() is quadratic in the number of properties. The plural insert()
rebuilds the metaobject only once.
