[fix](fe) Rewrite LogicalGenerate lateral conjuncts together with generators

[englefly]

What problem does this PR solve?

Problem Summary:

GenerateExpressionRewrite rewrote only LogicalGenerate.getGenerators() and rebuilt the node via withGenerators(), which preserved the lateral ON conjuncts unchanged. Whole-tree ExprId replacements (e.g. any_value wrapping of a group-by key in EliminateGroupByKeyByUniform / EliminateGroupByKey) that renamed a slot referenced by an ON conjunct therefore left the conjunct with a stale ExprId after the child switched to the wrapped slot, and final slot validation rejected the query:

Generate[UNNEST(tags#T2), ON tag#G = name#N]   // name#N is stale after the child outputs name#N2
  Project[..., name#N2, ...]
    Aggregate[..., ANY_VALUE(name)#N2, ...]

Fix: GenerateExpressionRewrite now rewrites getConjuncts() in the same operation and rebuilds the node with a new LogicalGenerate.withGeneratorsAndConjuncts() helper, so generators and lateral ON conjuncts stay consistent under any expression rewrite.

Release note

None

Check List (For Author)

• Test

  • Unit Test
    • New GenerateConjunctRewriteTest.testExprIdRewriterRewritesLateralConjuncts: builds a LogicalGenerate with a conjunct referencing a slot, runs ExprIdRewriter with an old->new ExprId map and asserts the conjunct is rewritten (fails on the old code: expected: 999 but was: <old id>).
    • Full GenerateConjunctRewriteTest / EliminateGroupByKeyByUniformTest / MergeGeneratesTest / FdTest classes are green.
  • Regression test
  • Manual test (add detailed scripts or steps below)
  • No need to test or manual test. Explain why:

• Behavior changed:

  • No.
  • Yes.
    Internal correctness fix for plan rewriting; no intended plan-shape or performance change.

• Does this need documentation?

  • No.
  • Yes.
