We synthesize the MIR for a by-move body for the FnOnce implementation of async closures. It can be accessed with the coroutine_by_move_body_def_id query. We weren't encoding this query in the metadata though, nor were we properly recording that synthetic MIR in mir_keys, so the optimized_mir wasn't getting encoded either!

Stacked on top is a fix to consider DefKind::SyntheticCoroutineBody to return true in several places I missed. Specifically, we should consider the def-kind in fn DefKind::is_fn_like(), since that's what we were using to make sure we ensure query mir_inliner_callees before the MIR gets stolen for the body. This led to some CI failures that were caught by miri but which I added a test for.

hahah this is blocked on #130199, that's where the ci test failure comes from.

Encode `coroutine_by_move_body_def_id` in crate metadata

We synthesize the MIR for a by-move body for the `FnOnce` implementation of async closures. It can be accessed with the `coroutine_by_move_body_def_id` query. We weren't encoding this query in the metadata though, nor were we properly recording that synthetic MIR in `mir_keys`, so the `optimized_mir` wasn't getting encoded either!

Stacked on top is a fix to consider `DefKind::SyntheticCoroutineBody` to return true in several places I missed. Specifically, we should consider the def-kind in `fn DefKind::is_fn_like()`, since that's what we were using to make sure we ensure `query mir_inliner_callees` before the MIR gets stolen for the body.
