Commit Message

xds: Add ExtAuthzClientCall (#12897)

Introduces ExtAuthzClientCall, which buffers outgoing RPC frames while
performing async ext_authz checks. Because the authorization call is
asynchronous, outgoing sendMessage() and halfClose() frames are buffered
in ExtAuthzClientCall until a decision arrives. On allow, buffered
operations are replayed with any header mutations applied. On deny, the
call is terminated immediately.

Key classes:
- AuthzCallbackObserver — async listener on the authz gRPC stream that
signals the buffering call on completion.
- ExtAuthzClientCall — buffers outgoing frames while authz is pending;
drains or cancels based on the decision.
- MutatingClientCall — wraps the real call to inject header mutations
from the authz response.
- FailingClientCall / FailingCallWithTrailerMutations — immediate
termination paths for denied or disabled-filter scenarios.
