[dart2wasm] Use dynamic invocations to call closures when dynamic modules are enabled. Running with dynamic modules means that closure invocation shapes cannot be statically known. A closure can flow between any modules and can then be invoked with a shape that's unknown to the module that defines the closure. Given this, our 2 options are to generate code for every invocation shape or invoke the closure as if we don't know it's shape (dynamic invocation). The former would scale exponentially relative to the number of named parameters so is not practical. The latter generates slower, bigger code but is the more practical of the 2.

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.
See LICENSE and PATENT_GRANT.
