  Diagnose misuse of the cleanup attribute (#80040)

This pull request fixes #79443 when the cleanup attribute is intended to
be applied to a variable declaration, passing its address to a specified
function. The problem arises when standard functions like free,
closedir, fclose, etc., are used incorrectly with this attribute,
leading to incorrect behavior.

Fixes #79443
