This is an automated cherry-pick of #56609

What problem does this PR solve?

Issue Number: close #56603, close #56582

Problem Summary:

What changed and how does it work?

  1. If the CTE contain orderby/limit/distinct and CTE is referenced by another CTE recursive part, it cannot be inlined . Related issue Parsing CTE error with "doesn't yet support 'ORDER BY / LIMIT / SELECT DISTINCT in recursive query block" #56603
  2. If the CTE inside of view, the consumerCount of CTE cannot be updated because the view skip the preprocessor phase in during optimizer, it also cannot judge the inline or not. So the CTE inside of view will always be not inlined. Related issue The CTE inside of view can't determine whether it can be inlined #56582
