inspect.getframeinfo forces all lazy modules to be loaded

Bug report

Bug description:

Create two files as follows:

main.py:

import importlib.util
import inspect
import sys

# https://docs.python.org/3/library/importlib.html#implementing-lazy-imports
def lazy_import(name):
    spec = importlib.util.find_spec(name)
    loader = importlib.util.LazyLoader(spec.loader)
    spec.loader = loader
    module = importlib.util.module_from_spec(spec)
    sys.modules[name] = module
    loader.exec_module(module)
    return module
    
lazy_import('m')

f = inspect.currentframe()
inspect.getframeinfo(f)

m.py:

print("I'm loaded!")

Now run:

$ python main.py 
I'm loaded!

This behavior doesn't make much sense, since f isn't even inside m.

CPython versions tested on:

3.13

Operating systems tested on:

先從 main.py 和 m.py reproducer 開始，然後追蹤 inspect.getframeinfo(f) 以及報告中所示的 lazy-import 設定。完成的標準是，對 m.py 外部的 frame 呼叫 inspect.getframeinfo 不再列印 "I'm loaded!"；請注意，連結的 PR gh-151006 表示相關工作已經在進行中。
