net/disk_cache/sql: Implement serial execution for checkpoint. Currently, SqlPersistentStore::MaybeRunCheckpoint executes checkpoints on all shards concurrently. Since checkpointing involves frequent disk access, concurrent execution might lead to disk contention and inefficiency. This CL introduces a new feature param `kSqlDiskCacheSerialCheckpoint`. When enabled, checkpoints are executed serially across shards. It adds `SqlPersistentStore::RunNextCheckpoint` to handle serial execution, accumulating results from each shard. The existing `WalCheckpoint` test is refactored into `RunWalCheckpointTest` to verify behavior with both serial and concurrent execution, and with single or multiple shards.
