Aske Simon Christensen 6faa5f3bd0 [dart2wasm] Initial commit for the Dart-to-WasmGC compiler.
This is work in progress. Several language features are still
unimplemented or only partially implemented.

Instructions for running the compiler and its output can be found in
pkg/dart2wasm/dart2wasm.md. These procedures are preliminary and
expected to change.

The best version of d8 to use for this version of dart2wasm is 10.0.40,
as explained here: https://dart-review.googlesource.com/c/sdk/+/232097

This commit also adds a dart2wasm-hostasserts-linux-x64-d8 testing
configuration to run the compiler over the test suite.

The history of the prototype that this is based on can be seen here:
