importlib.resources.files() doesn't work correctly when importlib library is compiled

Bug report

Bug description:

If importlib library is compiled (in particular _common.py), then any package, that uses bare files() to get its resources, breaks, because _infer_caller returns wrong frame (as mentioned in https://github.com/python/cpython/pull/123037#issuecomment-2294431430, __file__ in https://github.com/python/cpython/blob/35d8ac7cd7ed6cd3d84af721dce970da59bd5f68/Lib/importlib/resources/_common.py#L96 is not valid)

Reproducer:

import importlib
import os
import pathlib
import py_compile
import shutil
import sys
import tempfile
import textwrap


def compile(tempdir):
    target_dir = pathlib.Path(tempdir) / 'cimportlib'
    souce_dir = pathlib.Path(importlib.__file__).parent
    shutil.copytree(souce_dir, target_dir, ignore=lambda *_: ['__pycache__'])

    for dirpath, _, filenames in os.walk(target_dir):
        for filename in filenames:
            if filename != "_common.py":
                continue
            source_path = pathlib.Path(dirpath) / filename
            cfile = source_path.with_suffix('.pyc')
            py_compile.compile(source_path, cfile)
            pathlib.Path.unlink(source_path)


def create_package(tempdir):
    package_dir = pathlib.Path(tempdir) / 'somepkg'
    package_dir.mkdir()
    contents = {
        "__init__.py": textwrap.dedent(
            """
            import cimportlib.resources as res
            val = res.files().joinpath('resource.txt').read_text(encoding='utf-8')
            """
        ),
        "resource.txt": "data",
    }

    for file, content in contents.items():
        path = pathlib.Path(package_dir) / file
        path.write_text(content)


def main():
    with tempfile.TemporaryDirectory() as tempdir:
        compile(tempdir)
        create_package(tempdir)
        sys.path.insert(0, str(tempdir))
        print(importlib.import_module('somepkg').val)


if __name__ == "__main__":
    raise SystemExit(main())

Expectation:

data

Actual outcome:

FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmpngnuw441/cimportlib/resources/resource.txt'

It may be important for frozen python applications, as they don't include source code

从 Lib/importlib/resources/_common.py 开始，重点查看 _infer_caller 和所引用的行，然后使用已编译的 _common.py 通过提供的脚本重现该故障。将预期的数据输出与 FileNotFoundError 进行比较；当重现程序能够在已编译的 importlib 中运行，且正常的资源加载没有回归时，即表示完成。
