Update `TypeSystemSwiftTypeRef::GetTriple` to make use of an available target. With this change, `GetNameImporter` can work in more cases, since it only needs a triple. And since `GetNameImporter` can be expected to return a `ClangNameImporter` instance, the fallback to using Swift ASTContexts can be removed. This eliminates another case of unnecessarily loading Swift ASTContexts, which incurs a one time overhead that should only be paid when required. Partial follow up to #6654 (cherry-picked from commit f097595)
