Set type information of VIEW variables without explicit types

[MarkusAmshove]

Currently the variables parsed in a VIEW that don't have an explicit type don't have any type information at all.

This should be changed, because the types can be read from the DDM.

• If the ViewParser finds the corresponding DDM, it can add type information for every variable.
• If the defined variable in the VIEW is not found in the DDM, then it can be flagged as unresolved reference
