This adds support for adding the `--wasm` flag to `flutter run` and `flutter drive`
* Emits errors if you attempt to use the skwasm renderer without the `--wasm` flag
* Emits errors if you try to use `--wasm` when not using a web device
* Uses the skwasm renderer by default if you pass `--wasm` and no `--web-renderer`
* 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
This updates the framework to provide higher level wrappers around ui.instantiateImageCodecWithSize(). Functionally, this doesn't change anything (other than deprecating the older loadBuffer() method in favor of loadImage()), but it sets the stage for a simpler change that will allow us to provide a more flexible way to load sized images.
