[dart2wasm] Implement the three-pronged WasmGC type hierarchy. This splits the type hierarchy into three separate hierarchies with the top types `any`, `func` and `extern`. Update d8 to 10.6.91, which switches to the new type hierarchy. Also, all ref shorthands for abstract heap types are now nullable, so the type emitter in the `wasm_builder` is updated to follow that scheme. To reduce confusion about the nullability of abstract reference types, these now all require the nullability to be specified explicitly.

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
