[analyzer] Enforce diagnostic argument types at runtime. A mechanism is added to allow the types of diagnostic arguments to be checked at runtime. This mechanism is enabled for all analyzer diagnostic codes except for syntactic errors (since those are generated by the shared parser using the CFE's argument substitution mechanism, which is already strongly typed). To avoid introducing backwards incompatibilities to analyzer clients, the types are only checked at runtime if the diagnostic code implements the new `DiagnosticCodeWithExpectedTypes` interface. The expected types are determined by the type annotations in the `messages.yaml` file. These are the same type annotations used in the new literate API for diagnostic error reporting. So this should ease the transition into the new literate API, which will make any such type errors into compile-time errors.

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.
