Why not just forward it to the upstream provider?

Draft PR: Implements SEP-1046 (modelcontextprotocol/ext-auth#3, https://github.com/modelcontextprotocol/ext-auth/blob/main/specification/draft/oauth-client-credentials.mdx).
Motivation and Context
The Client Credentials flow enables machine-to-machine authentication without user interaction. This flow requires pre-registered client credentials, which are typically established out-of-band through administrative channels. Dynamic Client Registration is not used in this flow.
How Has This Been Tested?
Unit tests added.
