Jon Ross-Perkins 8779b8f64b Replace pending generic logic with work stack-based logic (#6404) 
This continues work to eliminate pending generics/specifics and get them
to be interleaved with instruction imports. I'm trying to use
`FinishGenericOrDone` here as a way to help ensure that code correctly
handles generics, where the simple alternative would be for each
`TryResolveTypedInst` call `SetGenericData` directly (but which might
make it easier to call the wrong `ResolveResult` function, and we do
need the `GenericId`s to be passed).
