Overloaded class methods not supported by Protocol

Bug Report

If a Protocol contains a class method, a class (or an object of this class) won't fulfill the Protocol if the class method is overloaded.

To Reproduce

from typing import Protocol, overload


class SupportsFooOnClass(Protocol):
    @classmethod
    def foo(cls, x: int) -> str: ...


class Fooer:
    @overload
    @classmethod
    def foo(cls, x: int) -> str:
        ...
        
    @overload
    @classmethod
    def foo(cls, x: float) -> complex:
        ...
        
    @classmethod
    def foo(cls, x: int | float) -> str | complex:
        if isinstance(x, int):
            return "foo"
        return 5j
        

def use_foo(fooable: SupportsFooOnClass):
    pass


use_foo(Fooer())
use_foo(Fooer)

Expected Behavior

Success.
Class Fooer supports a class method foo with one argument of type int and return type of str.
The same code passes pyright's check.

Actual Behavior

main.py:31: error: Argument 1 to "use_foo" has incompatible type "Fooer"; expected "SupportsFooOnClass"  [arg-type]
main.py:31: note: Protocol member SupportsFooOnClass.foo expected class or static method
main.py:32: error: Argument 1 to "use_foo" has incompatible type "type[Fooer]"; expected "SupportsFooOnClass"  [arg-type]
main.py:32: note: Protocol member SupportsFooOnClass.foo expected class or static method

Your Environment

• Mypy version used: 1.7.1
• Mypy command-line flags: -
• Mypy configuration options from mypy.ini (and other config files): -
• Python version used: 3.10

Start by running the minimal Python reproduction from the issue and compare mypy's handling of the Protocol, overloaded class method, and direct class or instance calls. Trace the Protocol compatibility check and overload handling, then verify that both use_foo(Fooer()) and use_foo(Fooer) pass without errors while preserving the existing overload behavior.
