[Feature] add uuid as the table unique identity

### Search before asking

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

### Motivation

Can paimon add a table attribute uuid as the table unique identity.
A UUID that identifies the table, generated when the table is created.
Implementations must throw an exception if a table's UUID does not match the expected UUID after refreshing metadata.
So far, can only use catalog name + database name + table name + table create time to generate unique identifiers.
In the OLAP scenario, getting the create time spent a lot of time.

The issue names no files, tests, or entry points. Start by locating the table-creation and metadata-refresh paths, then determine how a generated UUID would be stored, exposed, and validated against the expected identity after refresh.
