[dart2wasm] Implement --omit-bounds-checks flag Similar to dart2js --trust-primitives, with --omit-bounds-checks (implied by -O4) we omit bounds checks in standard library list and typed array indexing methods, such as `operator []` and `[]=`. For now this flag does not omit range checks in functions like `setRange` and `setAll`: - Functions like `setRange` do more work than functions like `[]` and `[]=`, and bounds checks are a smaller part of the whole operation. - For the same reason, and also because they either don't return any values or have to return boxed (i.e. `getRange` needs to return an `Iterator`), inlining them is not as crucial as inlining an `Uint8List.[]` implementation (which avoids boxing when inlined). Closes #54962. Tested: dart2wasm change with small refactoring in VM, tested with existing tests.

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).
Dart is free and open source.
