  shared/bap: Skip local metadata Config callbacks

When reconfiguring a client stream that is already Codec Configured,
setup_config() queues Codec Configuration and then caches metadata.
stream_metadata() emits a same-state CONFIG notification for that local
update. The profile callback treats it as the peer's configuration
completion and clears config_pending before the peer has responded.

If the control point response precedes the ASE state notification, QoS
setup can run while need_reconfig is still set and fail locally.

Cache client metadata in CONFIG without emitting a state notification.
Keep genuine peer CONFIG notifications and server metadata handling
unchanged.

  test-functional: Cover BAP metadata reconfiguration

Exercise the real daemon by clearing a configured unicast endpoint and
reconfiguring its retained ASE with empty or Media-context metadata.
Require successful configuration and check the resulting transport.

Use ATT MTU 48 to prevent the control-point response and fresh ASE
notification from being batched together. Without the shared/bap fix,
the Media case fails QoS setup; the empty-metadata control still passes.

Call SetConfiguration directly because endpoint.config does not pass
metadata for unicast presets. Remove the fixture's redundant config
command: SelectProperties already configures both ASEs after pairing.
