### Purpose <!-- Linking this pull request to the issue --> Linked issue: close #1790 <!-- What is the purpose of the change --> [core] supports asynchronous deletion of expired snapshot files. I copied 3 files from `flink` repository to help implement: `ManuallyTriggeredScheduledExecutorService`、`ScheduledTask` and `DirectExecutorService` Note: currently only `snapshot` files support asynchronous deletion, and the other expired files such as `tag` and `partition` are still deleted synchronously. If necessary, it can be implemented in a subsequent PR. ### Tests Added `org.apache.paimon.operation.AsyncFileStoreExpireTest#testAsyncCleanFiles` to verify correctness. ### API and Format <!-- Does this change affect API or storage format --> No ### Documentation <!-- Does this change introduce a new feature --> No -- This is an automated message from the Apache Git Service.
