extension: disable some optimizations for extension function (#51926)

[ti-chi-bot]

This is an automated cherry-pick of #51926

What problem does this PR solve?

Issue Number: close #51925

Problem Summary:

If an extension function has some side-effect, it may be optimized by mistake. For example, if a function myfunc returns a random int, select id, myfunc() from t may produce same values for myfunc because it have been fold to a constant.

Another problem is that if an extension function requires some privilege, it will only be checked when building it. That causes some problems when the plan cache is enabled because the privilege will not be check again when evaluating a function and a user's privileges may be revoked.

We should avoid these unnecessary optimizations.

What changed and how does it work?

Disable some optimizations for extension functions.
