This adds a --platform= option to dart2wasm to read the SDK libraries from that dill file instead of compiling them from source every time. If the option is not given, the SDK libraries are compiled, like before. Also adds a "dart2wasm" build target, which will build the dart2wasm platform dill and compile dart2wasm to two AOT snapshots (with and without asserts). The dart2wasm scripts in sdk/bin are updated to run via these snapshots and use this platform dill. This speeds up test runs for the dart2wasm-hostasserts-linux-x64-d8 configuration by approximately 45x.
