enhance: add all-replicas-ready checkpoint metric for query coord (#48305)
The existing current_target_checkpoint_unix_seconds metric advances as
soon as any single replica is ready per channel, which does not reflect
the true minimum state of the cluster in multi-replica mode.

Add a new metric current_target_all_replicas_checkpoint_unix_seconds
that only updates when all replicas have at least one ready delegator
for a given channel, correctly reflecting the cluster-wide minimum
checkpoint state.

issue: #48304
