planner: add table info into context in fast plan case

[sdojjy]

What problem does this PR solve?

We forgot to add table info into session context in fast-plan case, so the audit log plugin can know which tabled is affected by the user.

What is changed and how it works?

Add table info when building PointGetPlan

Check List

Tests

• Manual test (add detailed scripts or steps below)

step1: build and run tidb with audit plugin enabled.
step2: config the audit plugin

insert into tidb_audit_table_access(user,db, tbl, access_type) values ("","","","");

step 4: run point get, point update, point delete query.
step 3: check if the audit log containers the table info
