576: fix Drop of uninit Ctx; use MaybeUninit r=MarkMcCaskey a=MarkMcCaskey I'm somewhat concerned that we need to call `intrinsics::panic_if_uninhabited::<T>();` or something to tell the compiler that we know it's safe. We just reinterpret the pointer later as initialized which is safe in theory due to `repr(transparent)` this should unblock #561 Co-authored-by: Mark McCaskey <[email protected]>
