issue: #47178
This commit introduces a rate limiting mechanism for Write-Ahead Logging
(WAL) operations to prevent overload during high traffic. Key changes
include:
- Added `RateLimitObserver` to monitor and control the rate of DML
operations.
- Add Adaptive RateLimitController to apply the strategy of rate limit.
- WAL will slow down if the recovery-storage works on catchup mode or
node memory is high.
- Updated `WAL` and related components to handle rate limit states,
including rejection and slowdown.
- Introduced new error codes for rate limit rejection in the streaming
error handling.
- Enhanced tests to cover the new rate limiting functionality.
These changes aim to improve the stability and performance of the
streaming service under load.

issue: #47647
Refactor the cluster-level broadcast mechanism to decouple the message
package from the channel registration lifecycle:
- Replace internal provider pattern with opaque ClusterChannels type
passed externally to WithClusterLevelBroadcast()
- Add channel package singleton (syncutil.Future) exposing
GetClusterChannels() and GetPChannelNames() blocking accessors
- Add PChannel() interface to MutableMessage/ImmutableMessage for
deriving physical channel from virtual channel
- Validate non-control-channel entries are physical channels using
funcutil.IsPhysicalChannel and use funcutil.IsOnPhysicalChannel for
control channel matching
- Move control channel substitution logic into WithClusterLevelBroadcast
to simplify callers (datacoord, coordinator, assignment service)
- Add lock interceptor unit tests and cluster broadcast test coverage
- Add integration test for FlushAll with streaming node restart to
verify data integrity across node lifecycle

- The DDL executing order of secondary keep same with order of control
channel timetick now.
- filtering the control channel operation on shard manager of

- Just implement exclusive broadcaster between broadcast message with
same resource key to keep same order in different wal.
- After simplify the broadcast model, original watch-based broadcast is
too complicated and redundant, remove it.
