Description

Problem*

Initial work towards #2334

Summary*

This is work towards allowing higher-order functions to be called with closure arguments. The bulk of the work will be done in the monomorphizer in the next PRs, this is a prerequisite that allows higher-order functions called with closures to pass type-checking.

A method called try_unify_allow_incompat_lambdas is added that is used instead of try_unify for function arguments. The only difference between it and try_unify is that it doesn't check function type capture groups.
This also fixes some comments that reference the removed make_subtype_of functions
