Move size assertions for `mir::syntax` types into the same file

A redundant size assertion for `StatementKind` was added in rust-lang#122937, because the existing assertion was in a different file.

This PR cleans that up, and also moves the `TerminatorKind` assertion into the same file where it belongs, to avoid the same thing happening again.
