Followup #38525 Previously, we use sequence number to generate partition id of table in hive metastore. for example, there are 2 partitions: `dt=2024-10-02` and `dt=2024-10-03`, the partition id will be 0 and 1. But if a new partition being added： `dt=2024-10-01`, the partiton id will be 0, 1, and 2. You can see, before, the id `0` is for `dt=2024-10-02`, but now `0` is for `dt=2024-10-01`. This PR use catalog/db/table/partition name to generate a id for the partition, so that each partition will have unique id.
