chore(action): update cibuildwheel arguments passing

[mayeut]

Only pass arguments that were set by the action to cibuildwheel.

Also add tests for action only & config-file arguments.

This allows to remove the workaround for pwsh update in #1741.

IMHO, this also brings some clarity when looking at the command-line that's being run:
e.g. https://github.com/pypa/cibuildwheel/actions/runs/7853848516/job/21433975640#step:8:64

Run if ($PSNativeCommandArgumentPassing) {

will now produce:

Run & "C:\hostedtoolcache\windows\Python\3.12.1\x64\python.exe" -m pipx run --spec "D:\a\cibuildwheel\cibuildwheel\./" cibuildwheel "sample_proj" --output-dir "wheelhouse"
