[fix](mv) Isolate temporary MV pre-rewrite state

[morrySnow]

What problem does this PR solve?

Issue Number: None

Related PR: None

Problem Summary:

MV pre-rewrite normalizes CTE children before the main rewrite. It reused the main statement context, allowing temporary CTE producer and consumer caches to affect later privilege checking and leaving partial CTE maps that could fail with an internal error.

This change gives temporary pre-rewrite its own mutable statement state while keeping ID and generated-alias allocation in the original statement scope. It temporarily installs the isolated context for utilities that access the connection directly and restores the original context in a finally block.

The regression test creates a view for which a user can select one column but not another, then exercises direct access and CTE queries under both default and forced pre-rewrite strategies. All paths must return the same permission error.

Release note

None

Check List (For Author)

• Test:
  • Regression test
  • Unit Test
  • Manual test
• Behavior changed:
  • Yes. MV pre-rewrite can no longer bypass or replace view-column privilege errors.
• Does this need documentation?
  • No.
