make hot reload reflect changes to asset transformer configurations (#144660)
In service of https://github.com/flutter/flutter/issues/143348 This PR makes hot reloads reflect changes to transformer configurations under the `assets` section in pubspec.yaml. This PR is optimized for ease of implementation, and should not be merged as-is. If it is merged as-is, seriously consider creating a tech debt issue and assigning it to someone to make sure it gets resolved.
