Allow a symbol to be passed to `attribute`, in place of a type object

The same is not true of `define_attribute`, which is meant to be the low
level no-magic API that sits underneath. The differences between the two
APIs are:

- `attribute`
  - Lazy (the attribute will be defined after the schema has loaded)
  - Allows either a type object or a symbol
- `define_attribute`
  - Runs immediately (might get trampled by schema loading)
  - Requires a type object

This was the last blocker in terms of public interface requirements
originally discussed for this feature back in May. All the
implementation blockers have been cleared, so this feature is probably
ready for release (pending one more look-over by me).
