* refactor(meta): simplify stream metrics collection with Drop pattern

Replace OnCompleteStream and Arc<AtomicU64> with a simple MetricsCollector
struct that uses Drop trait to log metrics when the stream completes.

Key improvements:
- Removed OnCompleteStream wrapper - no longer needed
- Replaced Arc<AtomicU64> with plain u64 in MetricsCollector

refactor(meta-service): move raft to separate runtime (#18777)

* refactor(meta-service): move raft to separate runtime

Since this commit, servers such as gRPC, raft-API, HTTP-API runs in the
main runtime, raft and its related tasks, such as state machine and
compactor, network are moved to another runtime.

So that when databend-meta running in heavy load, the service layer
won't be affected.
