Revamp workflowtask "Input filters" tab

[tcompa]

1. New name is "types"
2. The first block is the same as we have now. Set arbitrary-key type filters or select one from the available type filters. Maybe in the future we can also expose available workflow filters - not for this issue.
3. Read-only display of workflowtask.task.input_types / output_types

What about the same information that is already displayed in the Info tab (always on the workflow page)? Should I remove it?

Yes, we don't need to show this on the info page anymore in my view, this can now fully just be displayed on the Types tab
