[fix](catelog) Unifies partition items string (#45669)

### What problem does this PR solve?

Issue Number: close #xxx

Related PR: #xxx

Problem Summary:

For range partitions, `getItems().toString()` is equal to
`getItemsString`, but for list partitions, there has a `,` between each
item.

The upsert record of binlog is generated via `getItemsString`, but the
getMeta method fetches partition items string via
`getItems().toString()`, which are different in the list partitions, and
the ccr-syncer is unable to identify them.

This PR unifies all partition items string via `getItemsString`.
