chore: missing type for parameter in autosize (angular#8906)

* The ``MatTextareaAutosize` directive misses a type for the `resizeToFitContent` method. The `gulp api-docs` task showed that the type is missing.
* Improves the `normalizeMethodParameters` method in the Dgeni setup, to also add type information to parameters that have been parsed properly by Dgeni, but still miss a type.
