Front end: move anonymous mixin sealed/final inference to checkSupertypes phase.

Previously this step happened during `buildOutlineNodes`, but since
`buildOutlineNodes` happens in source order, this means that anonymous
mixins would only get their sealed and final attributes properly
inferred if they appeared *after* their immediate supertypes in source
order.  By moving this step to `checkSupertypes`, we ensure that the
computation is correct regardless of source order, because
`checkSupertypes` happens in class hierarchy order.

Fixes #52048.
