[red-knot] Add __init__ arguments check when doing try_call on a class literal (#16512)

## Summary

* Addresses #16511 for simple cases where only `__init__` method is
bound on class or doesn't exist at all.
* fixes a bug with argument counting in bound method diagnostics

Caveats:
* No handling of `__new__` or modified `__call__` on metaclass.
* This leads to a couple of false positive errors in tests

## Test Plan

- A couple new cases in mdtests
- cargo nextest run -p red_knot_python_semantic --no-fail-fast
