    stdlib: add missing stdc_rotate_right_ull alias when builtin is available
    
    When __builtin_stdc_rotate_right is supported, glibc defines type-specific
    aliases for several unsigned integer types (uc, us, ui, ul), but omits the
    unsigned long long variant. This leads to an inconsistency between the
    builtin-backed path and the generic fallback, where unsigned long long
    is handled.
    
    Add the missing stdc_rotate_right_ull macro mapping to
    stdc_rotate_right(__x, __n) to complete the set of type-specific helpers
    and ensure consistent API coverage across all supported unsigned integer
    types.
    
    No functional change for existing users; this only exposes the expected
    alias for unsigned long long.
    
    Fixes: 331c7a4cd0ee ("stdbit: Fix builtin name used in __glibc_has_builtin check for rotate_right")
