BLD: Lint for invalid files in wheels / packages

[TomAugspurger]

We should be able to catch things like conda-forge/pandas-feedstock#41 (comment) as part of our CI.

[jbrockmendel]

is this about linting we do at PR-time or at release-time or [...]?

[TomAugspurger]

PR time I think.

[mroeschke]

I think this should largely be handled once we have cibuildwheel in place #44027 (PR: #48283) which also tests the wheels so I think we can close this as falling under that issue
