DDL: Fix bug that TiFlash replica unavailable after add partition with small probability

[hehechen]

Issue Number: close #39171

Problem Summary:
There is a small probability that TiFlash replica unavailable after add partition.
refreshTiFlashTicker don't check if logical table is available, so if a partition has been added in AddingDefinitions of tableInfo, and have not been added in AvailablePartitionIDs, and refreshTiFlashTicker is executed at this time, this new added partition will be considered unavailable, so it will get TiFlash replica progress and then update available of the logical table.

What is changed and how it works?

Check if logical table is available in refreshTiFlashTicker.
