LUAU_FASTFLAGVARIABLE(flag) — defines a static (non-dynamic) bool FastFlag.
Reference: luau/Common/include/Luau/Common.h.
C++ expands to namespace FFlag { FValue<bool> flag(#flag, false, false); }.
Rust modules aren’t open like C++ namespaces, so the macro emits a bare
pub static at the call site (no per-flag mod, which would collide when a
file defines two flags); the enclosing per-crate FFlag module supplies the
namespace, so reads stay FFlag::flag -> crate::FFlag::flag.get().
