Getting started adding SwiftBuild rspm dep

Seeing the following error when running this `bazelisk build @swiftpkg_swift_build//:SwiftBuild.rspm`:

```terminal
error: ambiguous implicit access level for import of 'TSCBasic'; it is imported as 'private' elsewhere
    |        `- note: silence these warnings by adopting the upcoming feature 'InternalImportsByDefault'
```
