Parse OAuth Authorization header when request omits client secret (#21351) (#21374)
Backport #21351

This fixes error "unauthorized_client: invalid client secret" when
client includes secret in Authorization header rather than request body.
OAuth spec permits both:
https://www.rfc-editor.org/rfc/rfc6749#section-2.3.1

Clients in possession of a client password MAY use the HTTP Basic
authentication scheme ... Alternatively, the authorization server MAY
support including the client credentials in the request-body

Sanity validation that client id and client secret in request are
consistent with Authorization header.

Improve error descriptions. Error codes remain the same.
