What problem does this PR solve?

Issue Number: close #37187

Problem Summary:
The prepare and execute statements both will build the plan. But some code path in planBuilder have some assumptions about they only execute once.

What is changed and how it works?

  1. Record the actualColLen in last.InsertStmt for reusing.
  2. Initlizate the actualColLen to 0 not 1. Because it's safe and easy to handle.

Because the initialization value for insert.ColLen is 0. And it's impossible for the variable actualColLen's end value be zero(I guess. In code, it will be assigned to actualColLen = selectPlan.Schema().Len()). So we change the actualColLen's initiation value to 0.
