Aske Simon Christensen 2846cb8da6 [dart2wasm] Add Wasm bottom heap types ...

- Add getters for the top and bottom types of the WasmGC hierarchy
  that a type belongs to.
- Rename the internal common supertype from `top` to `common` to avoid
  confusion with the top type of each hierarchy.
- Always use a bottom type when emitting a `ref.null` instruction.
- Translate the `Null` and `Never` Dart types to WasmGC `nullref`.
