 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.

 Test Plan: make test TEST=T14204
