Use HashStable_Generic in rustc_type_ir

A lot of the types in this crate implemented HashStable directly to
avoid circular dependencies. One way around that is to use
HashStable_Generic. We adopt that here to avoid a lot of boilerplate.

This doesn't update all the types, because some would require
`I: Interner + HashStable`.
