Summary Do not deref CreationData's buffer when Cairo font is destroyed.

Since 263084@main `FontCustomPlatformData` takes `FontPlatformData::CreationData` instead of `FragmentedSharedBuffer`. The buffer is now a reference counted field of `FontPlatformData::CreationData` struct and will be automatically dereferenced when `FontCustomPlatformData` is destroyed. It is an error to manually dereference it using Cairo font destroy function.
