Implement SEP-991: URL-based Client Registration (OAuth Client ID Metadata)

This is a tracking issue for implementation of SEP-991.

Summary

This SEP adopts OAuth Client ID Metadata Documents as an alternative client registration mechanism, allowing clients to use HTTPS URLs as client identifiers where the URL points to a JSON document containing client metadata. The Python SDK needs to implement support for accepting HTTPS URLs as client_id values, fetching and validating client metadata documents from those URLs, and enabling servers to implement flexible trust policies for URL-based client registration without requiring pre-coordination.
