Hiroshi Yamauchi 3e6befd994 [IRGen] Size @_rawLayout types by the opaque lowering of the like type (#92826) ...

The storage of a `@_rawLayout(like: T)` type is accessed generically, so
size it using the opaque lowering of `T`. Previously, `Mutex<Void.Type>`
reserved no space for its value, so storing the value overwrote the lock
and `withLock` crashed.
