changefeed: fix add partition in old owner

[amyangfei]

What problem does this PR solve?

When TiCDC meets partition table update, the owner diffs the latest partition table information with the memory information, the new added partition and dropped partition should be calculated by

new added = Set(partition table IDs in latest table info) - Set(partition table IDs that TiCDC maintains)
dropped = Set(partition table IDs that TiCDC maintains) - Set(partition table IDs in latest table info)

The new added partition calculation is wrong, the affected version includes >=4.0.2, >=5.0.0.

5.1.0 and master are not affected.

What is changed and how it works?

Should use oldIDs as the partition table IDs that TiCDC maintains
