issue: #45841
- CPP log make the multi log line in one debug, remove the "\n\t".
- remove some log that make no sense.
- slow down some log like ChannelDistManager.

- Core invariant: logging is purely observational — this PR only
reduces, consolidates, or reformats diagnostic output (removing
per-item/noise logs, consolidating batched logs, and converting
multi-line log strings) while preserving all control flow, return
values, and state mutations across affected code paths.
- Removed / simplified logic: deleted low-value per-operation debug/info
logs (e.g., ListIndexes, GetRecoveryInfo, GcConfirm,
push-to-reorder-buffer, several streaming/wal/debug traces), replaced
per-item inline logs with single batched deferred logs in
querynodev2/delegator (logExcludeInfo) and CleanInvalid, changed C++
PlanNode ToString() multi-line output to compact single-line bracketed
format (removed "\n\t"), and added thresholded interceptor logging
(InterceptorMetrics.ShouldBeLogged) and message-type-driven log levels
to avoid verbose entries.
- Why this does NOT cause data loss or behavioral regression: no
function signatures, branching, state updates, persistence calls, or
return values were changed — examples: ListIndexes still returns the
same Status/IndexInfos; GcConfirm still constructs and returns
resp.GetGcFinished(); Insert and CleanInvalid still perform the same
insert/removal operations (only their per-item logging was aggregated);
PlanNode ToString changes only affect emitted debug strings. All error
handling and control flow paths remain intact.
- Enhancement intent: reduce log volume and improve signal-to-noise for
debugging by removing redundant, noisy logs and emitting concise,
rate-/threshold-limited summaries while preserving necessary diagnostics
and original program behavior.

issue: #43897
- Return LastConfirmedMessageID when wal append operation.
- Add resource-key-based locker for broadcast-ack operation to protect
the coord state when executing ddl.
- Resource-key-based locker is held until the broadcast operation is
acked.
- ResourceKey support shared and exclusive lock.
- Add FastAck execute ack right away after the broadcast done to speed
up ddl.
- Ack callback will support broadcast message result now.
- Add tombstone for broadcaster to avoid to repeatedly commit DDL and
ABA issue.
