interpret: remove outdated FIXME

The rule about `repr(C)` types with compatible fields got removed from the ABI compat docs before they landed, so this FIXME here is no longer correct. (So this is basically a follow-up to https://github.com/rust-lang/rust/pull/130185, doing some more cleanup around deciding not to guarantee ABI compatibility for structurally compatible `repr(C)` types.)
