[dart2wasm] Remove special casing of noSuchMethod in dispatch table builder

So far we force-included the `noSuchMethod` selector in the dispatch
table, making us have an entry for each class id (i.e. a dense row).

This is wasteful for most cases, because there may be few (if any)
overrides of `noSuchMethod`.

So instead we use the same policy on how to call `noSuchMethod` as
with all the other selectors, namely if there's only a single target
we call it directly, if there's a few we may use a static polymorphic
dispatcher function and otherwise use dispatch table.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

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).
