refactor: move modules from utils to types

[Silvanoc]

Move modules defining types rather than utilities from linkml_runtime.utils to linkml_runtime.types.

Part of refactoring proposed in issue https://github.com/linkml/linkml/issues/2371

Important note: getting the changes that this PR tries to address effectively working requires a synchronized effort involving the repos linkml, linkml-runtime and linkml-model.

It's questionable if the effort is worth the gain...
