[Feature] Creating tag submission triggers

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.

### Motivation

When writing data triggers the generation of a tag, it is generally necessary to notify downstream applications. For instance, adding a new partition in Hive metadata or generating a _SUCCESS file in a directory. The tag submission strategy can be customized. The specific partition submission behavior is based on a combination of triggers and policies.

Trigger: The timing of partition submission, which can be based on the watermark corresponding to the time extracted from the partition, or based on processing time.

Policy: The strategy for partition submission. Built-in policies include generating a _SUCCESS file and submitting to the Hive metastore, but custom strategies can also be implemented.

The issue names no files, tests, or implementation entry points. Start by locating the existing tag, trigger, and policy code, then determine how watermark- and processing-time triggers can select partition-submission policies. Done should include the requested built-in and customizable submission behavior with coverage for the supported strategies.
