[dart2wasm] Don't use IDs as keys for export name mapping. We have means of serializing References and Constants directly, so it is unnecessary to generate IDs as indices. This does cause the export name mapping to get split up a little (just as callable reference IDs were stored separately from constant export IDs). This is because the kernel metadata repositories are serialized by the kernel's BinarySink, which correctly handles Constants, but cannot serialize References from the TFA'd component to the metadata of the un-TFA'd component. Meanwhile, the dart2wasm DataSerializer can serialize these References, but does not handle Constants. Therefore, the callable reference mapping is stored on the main module metadata (just as callable reference IDs were), while the constant mapping is stored in a metadata repository (just as constant IDs were). The exporter must then be aware of both of these to be used as a centralized interface.

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.
