Utilize py launcher on windows for pdm use and pdm venv

[p-rogalski]

Is your feature request related to a problem? Please describe.

Python interpreters can be specified for the commands pdm use and pdm venv. However the full path to the Python interpreter must be given.

Alternatively all the Python interpreters can be added to PATH, which creates a big mess on Windows, since all Python executables are named the same. This mess is solved by the py launcher on Windows: https://docs.python.org/3/using/windows.html#python-launcher-for-windows

Describe the solution you'd like

It would be really helpful if PDM could utilize the py launcher to find Python executables. Specifically if you could specify the same version selectors like for the py launcher. Some examples:

pdm use "3.10"                   # Use Python 3.10
pdm use "3.11-32"                # Use Python 3.11 (32 bit)
pdm venv create "3.9-64"         # Create venv with Python 3.9 (64 bit)
pdm venv create "3"              # Create venv with Python 3

The python finder nows reads from the same source as py so what is not working for now?

Ah my mistake, pdm use 3.10 and the like actually works. However, I found no way to specify the architecture (32/64 bit):

> pdm use 3.10  
Please enter the Python interpreter to use
0. C:\Users\p.rogalski\AppData\Local\Programs\Python\Python310-32\python.exe (3.10-32)
1. C:\Users\p.rogalski\AppData\Local\Programs\Python\Python310\python.exe (3.10)

> pdm use 3.10-32
[NoPythonVersion]: No Python interpreter matching 3.10-32 is found.

No you can't, just choose from the listed interpreters and I think it's just easy enough.

Ok fair enough, thank you for your time!
