Change literal representation to not truncate

Also shuffles around the organization of numeric literals and types,

Make shared kind the default only for generic functions
...
You almost never want a function with pinned type params. For
types, objects, resources, and tags, pinned types are actually often
more sane. For most of these, shared rarely makes sense. Only tricky
case is objs -- you'll have to think about the kinds you want there.

Don't ever raise unique kinds of pinned kinds to shared (again)

So *resource, ~resource, [resource] are all pinned. This is counter to the
design of the kind system, but this way is a much clearer path to type safety.
Once we've established a good baseline with lots of tests, then we can try to
make raising pinned kinds work.
