* Adds support for `flutter test --wasm`. * The test compilation flow is a bit different now, so that it supports compilers other than DDC. Specifically, when we run a set of unit tests, we generate a "switchboard" main function that imports each unit test and runs the main function for a specific one based off of a value set by the JS bootstrapping code. This way, there is one compile step and the same compile output is invoked for each unit test file. * Also, removes all references to `dart:html` from flutter/flutter. * Adds CI steps for running the framework unit tests with dart2wasm+skwasm * These steps are marked as `bringup: true`, so we don't know what kind of failures they will result in. Any failures they have will not block the tree at all yet while we're still in `bringup: true`. Once this PR is merged, I plan on looking at any failures and either fixing them or disabling them so we can get these CI steps running on presubmit. This fixes https://github.com/flutter/flutter/issues/126692
