JmPotato 0b32e6e185 feat(metering): add storage size metering and keyspace name caching (#9774) ... ref tikv/pd#9707 - Introduced storage size metering: - Added `storageSizeCollector` to periodically record row-based and column-based storage usage per keyspace. - Integrated with cluster metering writer for reporting. - Extended `RegionInfo` and statistics with `ApproximateColumnarKvSize` tracking. - Added keyspace name caching and lookup in `KeyspaceManager` for efficient resolution. - Extracted common metering utilities (`NewRUValue`, `NewBytesValue`, constants for source/fields) into `pkg/metering/utils.go`.
