[JIT] Skip builtins while enumerating class methods (#91805)

This is needed to support `enum.Enum` derived classes in Python-3.11
that adds `_new_member_` to classdict, see:
15c44789bb/Lib/enum.py (L529)

Following snippet illustrates the problem with the previous iteration of
the code on 3.11:
```python
from enum import Enum
import inspect

class Color(Enum):
    RED = 1
    GREEN = 2

def print_routines(cls):
    print(cls.__name__)
    for name in cls.__dict__:
        fn = getattr(cls, name)
        if inspect.isroutine(fn):
            print(name, fn, f"has_globals: {hasattr(fn, '__globals__')}")

print_routines(Color)
```
