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`.
