Check if -XStaticPointers is enabled when renaming static expressions
Summary:
Trying to use `static` expressions without the `-XStaticPointers`
extension enabled can lead to runtime errors. Normally, such a situation isn't
possible, but Template Haskell provides a backdoor that allows it to happen,
as shown in #14204.
To prevent this, we ensure that `-XStaticPointers` is enabled when renaming
`static` expressions.
