Common type in container is determined using constructor args

Bug Report

To Reproduce

from typing import Type, List


class NonLiskovChild(Exception):
    """Does not match Exception.__init__() signature"""
    def __init__(self, _some_other_arg: object) -> None:
        super().__init__()


types1 = [TypeError, ValueError]
reveal_type(types1)
# Revealed type is 'builtins.list[def (*args: builtins.object) -> builtins.Exception]'

types2 = [TypeError, NonLiskovChild]
reveal_type(types2)
# Revealed type is 'builtins.list[builtins.type*]'

# When explicitly setting the type, mypy accepts NonLiskovChild as an Exception subtype:
types3: List[Type[Exception]] = [TypeError, NonLiskovChild]
reveal_type(types3)
# Revealed type is 'builtins.list[Type[builtins.Exception]]'

Expected Behavior

The lowest common type should be determined by inheritance, not with __init__() signature matching.

Otherwise stdlib classes like CalledProcessError do not work correctly, e.g. in this example:

import pytest
from subprocess import CalledProcessError

with pytest.raises((TypeError, CalledProcessError)) as exc_info:
    pass
# error: Need type annotation for "exc_info"
# error: Argument 1 to "raises" has incompatible type "Tuple[Type[TypeError], Type[CalledProcessError]]"; expected "Union[Type[<nothing>], Tuple[Type[<nothing>], ...]]"

Your Environment

• Mypy version used: 0.910
• Mypy command-line flags:
• Mypy configuration options from mypy.ini (and other config files):
• Python version used: 3.8.10
• Operating system and version: Windows 10

Inizia riproducendo i due esempi di reveal_type e il caso pytest.raises dell’issue. Traccia come viene inferito il tipo comune del contenitore a partire dai costruttori delle classi, quindi verifica che le sottoclassi di Exception indicate producano i tipi inferiti attesi e nessun errore dovuto ad argomenti incompatibili.
