planner/core: fix a bug that check update privilege use wrong AsName and DBName

[tiancaiamao]

What problem does this PR solve?

Fix issue #8911

What is changed and how it works?

The 'privilege check fail' comes from the wrong visitInfo which is collected from update tb_wehub_server a set a.active_count=a.active_count+1,a.used_count=a.used_count+1 where id=1

The correct visitInfo should be

{check=update, db=weperk, table=tb_wehub_server}
{check=select, db=weperk, table=tb_wehub_server}

but we get

{check=update, db=, table=tb_wehub_server}
{check=select, db=, table=a}
{check=select, db=weperk, table=a}

• Check privilege should use table OrigName, instead of AsName
• Some col.DBName is not set, it should be CurrentDB name

Check List

Tests

• Unit test

Side effects

I find privilege check for OrigName is not a completely solved problem, some places may still use AsName.
I'll later go over the code and take a full check.
