planner: add basic support for column privilege

[tiancaiamao]

What problem does this PR solve?

Some tiny changes to support column level privilege.

What is changed and how it works?

In the old code, addVisitInfo is add in the buildDataSource, there is no column information there.
To support column privilege, the visited column information must be accurate.
So addVisitInfo is moved from buildDataSource to buildProjection where the column is available.

In buildUpdate, the column is set for addVisitInfo.
