Index-only plan step 3: Top-down Select and Join transformation rule

- Converted IntroduceSelectAccessMethodRule and IntroduceJoinAccessMethodRule

  from bottom-up approach to top-down approach from the root operator.

- Index-only plan needs to verify the variables that are live in the select or join condition

  are the only variables to be used afterwards unless a variable is generated after the select or join operator.

- In order to keep this information, top-down approach needs to be introduced.
