Issue 21826: Initial data structures and metatype for OIDC Private Key JWT client authn

[ayoho]

• Adds a private_key_jwt option to the tokenEndpointAuthMethod attributes in <openidConnectClient> and <oidcLogin>. **Note: ** This is still strictly beta-level code and remains incomplete.
• Adds a new PrivateKeyJwtAuthMethod class to encapsulate the logic for creating JWTs to use for client authentication.
