BUG: avoid relying on external packaging package in interchange protocol

[jorisvandenbossche]

I noticed this by accident, and we have a vendored version of packaging that we otherwise use internally.

(this might be a good case to add a code check for? cc @MarcoGorelli)

Thanks @jorisvandenbossche

can always raise an issue for this.

xref #41207, do we have an open issue to potentially remove this in the future?

@jorisvandenbossche which are the packages which pandas vendors? Just version and clipboard?

[jorisvandenbossche]

I am not directly aware of others (except for some C code). And probably packaging.version is the main relevant one, as clipboard / pyperclip might not be that common to use in normal code outside of the clipboard IO code
