Also renames variables of that type to match. A follow-up PR will rename `Parse::StateStackEntry` to `Parse::State`. This is more consistent with the naming of similar enums elsewhere in the toolchain, and with the prevailing practice of using `state` rather than e.g. `entry` as the name of a `StateStackEntry`.
