Support `--incompatible_objc_provider_remove_linking_info`

[luispadron]

In Bazel 7 a new flag: --incompatible_objc_provider_remove_linking_info was added to further delete these link attrs from the ObjcProvider making it an error if the attr is used or set. This will be flipped in a future Bazel version (probably Bazel 8). We should update our rules to conditionally forward ObjcProvider linking information to support this flag.

Example error you'd see with this flag enabled:
