`profile` and `cProfile` cannot profile a directory or PEP-441 zip file

Bug report

Python can execute zip files (PEP-441) and directories directly, e.g. python code.zip or python directory, if they're constructed appropriately (such as via zipapp or https://github.com/pantsbuild/pex). These don't work with profile or cProfile modules, e.g. python -m profile code.zip fails with ValueError: source code string cannot contain null bytes and python -m cProfile directory fails with IsADirectoryError: [Errno 21] Is a directory: 'directory'.

For example: https://gist.github.com/huonw/52574abce4057afd99abb5e4a7f82b61 has a simple __main__.py and a zip file that contains it:

import sys
print(f"Hello from {sys.argv[0]}")

There's a script that runs all 9 combinations of zip vs. file vs. directory, and no profiling vs. profile vs cProfile. It can be executed via:

git clone https://gist.github.com/huonw/52574abce4057afd99abb5e4a7f82b61
cd 52574abce4057afd99abb5e4a7f82b61
./script.sh

Output of script.sh:

updating: __main__.py (stored 0%)
Archive:  code.zip
 extracting: directory/__main__.py

IsADirectoryError: [Errno 21] Is a directory: 'directory'

Workarounds:

• for a zip, manually unzip, and then run the __main__.py, e.g. unzip code.zip -d directory && python -m cProfile directory/__main__.py.
• for a directory, run the __main__.py, e.g. python -m cPorfile directory/__main__.py

Your environment

• CPython versions tested on: 3.9.10, 3.10.4, 3.11.0
• Operating system and architecture: python -m platform == macOS-12.5.1-arm64-arm-64bit

Comienza por los puntos de entrada de módulo de profile.py y cProfile.py y, después, ejecuta el reproductor proporcionado script.sh para los casos de archivo, ZIP y directorio. Se considera terminado cuando ambos comandos de perfilado manejan archivos ZIP PEP-441 y directorios ejecutables sin el ValueError ni el IsADirectoryError indicados.
