lock --strategy no_cross_platform should list the wheels for different Python versions

[paugier]

When using pdm lock --strategy no_cross_platform (workaround for #2566), only the wheels for the Python version used during lock are listed.

[[package]]
name = "scipy"
version = "1.11.4"
requires_python = ">=3.9"
summary = "Fundamental algorithms for scientific computing in Python"
groups = ["doc", "full", "test"]
dependencies = [
    "numpy<1.28.0,>=1.21.6",
]
files = [
    {file = "scipy-1.11.4-cp39-cp39-manylinux_2_17_x86_64.manylinux2014_x86_64.whl", hash = "sha256:91af76a68eeae0064887a48e25c4e616fa519fa0d38602eda7e0f97d65d57937"},
    {file = "scipy-1.11.4.tar.gz", hash = "sha256:90a2b78e7f5733b9de748f589f09225013685f9b218275257f8a8168ededaeaa"},
]

Then, installing with another python version is broken because it tries to install from the sdist which usually does not work.

Expected behavior

cross_platform should be about the platform, not the Python version. The wheels for other Python versions should be listed.
