chore: Create xcframework-specific Cartfile.

Changes introduced in 721a15d aused GitHub checks to fail due to having
duplicate URLs in the Cartfile (see: https://github.com/googlemaps/maps-sdk-for-ios-samples/runs/5635557018)
This change fixes that error by moving xcframework-specific versioning
into its own file. Once this is submitted, I'll update our docs to point
to this new file (cl/437090767).

Verified that this change passes: https://github.com/googlemaps/maps-sdk-for-ios-samples/actions/runs/2036764574
