[OTHER] Update types of all models

[mehmetozsoy-synnada]

Summary

In mithril, since now types can be polymorphic, types should be updated accordingly. Therefore types of all primitives should be implemented

Second topic of this issue is that in mithril, we currently have some values in __call__() function. These values should be carried to the init of primitive functions.

Context

• Analyze all primitive functions of Mithril.
• Find types of all functions.
• Update type of primitives accordingly.
• Update init values of all primitive functions.
• change name cutoff to threshold
• update tests accordingly
