Remove Element.asType calls

These calls are not really reasonable as Element can be anything
(e.g. package) where type would be a NoType.
Instead of that undefined case, this CL replace asType calls with
an extension property (.type) and certain element where it makes
sense.

Even though we cannot enforse it right now, after the migration,
these fields will only exist in specific XElement subclasses so
we'll be able to enforse never getting type from XElement.
