feat(ios): ability to link local spm packages (#54405)

Summary:
Pull Request resolved: #54405

While working on local project in monorepo, I found that `spm_dependency` utility available in CocoaPods does not support local SPM packages, assuming they always come from remote.

This change extends it so that `url` can also be a local path:

```ruby
  spm_dependency(s,
    url: File.join(__dir__, 'shared'),
    requirement: {},
    products: ['FooModule']
  )
```

In the above example, `shared` folder contains a SPM project.

I don't have opinions on the API design here, I am also happy to create `spm_local_dependency` utility in order to clean up the API design.
