What problem does this PR solve?

Issue Number: close #38493

Problem Summary:

The StatementContext.Tables records the all tables/databases we are accessing in the statement. But some times it have some empty value (db == "" and table == "").

The reason is that the tables are from planBuilder.visitInfos , but it not only contains database/tables, it also contains some dynamic privilege visitInfos, so we should filter those visitInfos out.

What is changed and how it works?

filter out the visitInfos with dynamic privilege out.
