Closes https://github.com/dart-lang/sdk/issues/54381 - Adds an API to capture the this value so that users can use it in the callback. - Adds specialized stubs to dart2js similar to what was done for toJS. - Adds generic stub to DDC as these stubs don't get tree-shaken away and toJSCaptureThis is less likely to be used. - Modifies dart2wasm lowerings to add this to the JS function wrapper if calling toJSCaptureThis.
