expression: avoid Order By constant expression error when plan cache is enabled

[eurekaka]

What problem does this PR solve?

Issue Number: close #16203

Problem Summary:

Error is reported for order by rand() when plan cache is enabled.

What is changed and how it works?

What's Changed:

• remove Rand / Sysdate / UUID from DeferredFunctions, because they should not be folded into constant according to unFoldableFunctions, otherwise, they would be converted to a Constant with DeferredExpr in funcCallToExpression. This change makes the behavior regarding these functions consistent when plan cache is enabled / disabled.

• check if the order by items can be treated as constants during execution using a new function, instead of IsMutableEffectsExpr, which is specifically designed for de-duplicating expressions.

How it Works:

• planner: keep unfoldable exprs when pruning columns for ORDER BY items #10064: first fix for order by rand() when plan cache is disabled by using ConstItem();
• expression: fix constItem() and column-pruning in order by clause #11839: second fix for order by rand() when plan cache is disabled by using IsMutableEffectsExpr();

should we also cherry-pick this bugfix to release-2.1, release-3.0 and release-3.1?

@zz-jason plan cache is not GA for those branches, so we don't need cherry-picks for them?

[zz-jason]

Users may use plan cache in these old releases. If they met this bug and not willing to upgrade the cluster to release-4.0, maybe they can update there cluster to the latest version in the corresponding release branch.
