When the resolved IAuthorizationHeaderProvider implements IAuthorizationHeaderProvider2, pass the materialized HttpRequestMessage so SignedHttpRequest h/b claims can bind to the request body and headers. Falls back to the existing call when the provider is not request-aware, so behavior is unchanged for existing providers.

Use the AcquireTokenOptions request helper to make the outgoing HttpRequestMessage available to request-binding protocols (e.g. PoP SHR q/h/b) instead of the IAuthorizationHeaderProvider2 interface. The helper clones ExtraParameters before writing so concurrent calls never share this per-request value. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

What
Sets the materialized
HttpRequestMessageonAcquireTokenOptions(via the AbstractionsSetHttpRequestMessageextension) beforeCreateAuthorizationHeaderAsync, so request-aware providers can read it back.Why
SignedHttpRequest (SHR / PoP)
q/h/bbinding claims must bind to the outgoing request. The call site already setshttpRequestMessage.Contentbefore the auth header is created, so the request is available exactly where it's needed. Replaces the earlierIAuthorizationHeaderProvider2interface check — behavior is unchanged for providers that don't read the value.Depends on
