statistics: do not analyze non exist table anymore

[Rustin170506]

What problem does this PR solve?

Issue Number: close #57227

Problem Summary:

What changed and how does it work?

After #57222, we can handle most cases where tables have been dropped. However, there is still a chance that we might attempt to analyze a non-existent table or use incorrect information to perform the analysis.

In this PR, I check the schema and table information before performing the actual analysis. This helps minimize unnecessary analysis work.

Maybe we should put these fields into a substruct. But the PR is too big. I will do it later.

What about unifying the naming, like DBName/SchemaName, TableName and IndexesNames?
