[ddc] Use direct cast methods for primitive casts

The `_as` methods for primitive types are designed to be called from
both the `_as` selector and directly from generated code.

For the primitive types that are known at compile time and cannot change
via linking or hot reload, we can generate direct calls.

Adapted from https://dart-review.googlesource.com/c/sdk/+/420380

In addition to the base change:
* Remove `int` cast helpers from DDC only code in favor of the
  versions from dart:_rti.
* Moves existing optimizations from `visitAsExpression` to `_emitCast`
  to apply them consistently.

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).
