There was a moment during the refactor that I was thinking about getting
rid of the `__type__` attribute as the source of truth for the type
instance, but I think that was a bit more than I could chew. However I
forgot to re-add the default implementation for Obj::type_inst, so that
has been added back in.

I don't know if I'm ever going to get this right.
It's a massive pain having to pass around the base "Method" type
everywhere. It really makes a lot more sense to have it already defined
someplace statically available. It makes doing like getting an attribute
or vtable entry a lot more ergonomic. Previously we'd have to pass in
the Method type every time, which was silly. Now we can just let the
MethodInst::instantiate() function query it directly. Like, this is
100000% better.
Also, I got rid of get_attr_lazy in favor of get_vtable_attr. I think
that I want to unify get_attr and get_vtable_attr, but that would
require a GC pointer to the "self" object on every object that you
create. That's a bit iffy.
But for now, things are feeling a little better and all the tests are
passing, so that's good at least.
