Add UCP_EP_ATTR_FIELD_ESTIMATED_BW field to ucp_ep_attr_t that allows querying the estimated aggregate bandwidth (bytes/sec) for a given local/remote memory type pair on an endpoint. The caller sets local_mem_type and remote_mem_type and the implementation returns the sum of bandwidths across all data lanes whose memory domain supports the requested memory type. Closes openucx#6254

CI failures are infrastructure flakes on RoCE workers, unrelated to the bandwidth query API change:
None of these tests exercise the ucp_ep_query path. Retriggering CI. |
