Before this change, having an Android app depend on a plugin that has no android implementation resulted in a Gradle build failure.
This scenario is likely to become more common if we're enabling federated plugins, as the package implementing just the desktop implementation of a plugin won't have an Android implementation.
This changes the Gradle plugin to not try to build any plugins that doesn't have an android/build.gradle file.
This reverts commit af9f424d5d.
Reverts flutter/flutter#39439
Reason: this passed the local device lab test on my Macbook but it failed in the actual device lab. Will investigate, fix, and reland.

For https://github.com/flutter/flutter/issues/33899
Test added:
- simple_animation_perf_ios
Test modified:
- backdrop_filter_perf_ios__timeline_summary
We'll add the CPU/GPU measurement to more iOS tests
once it's proven to be non-flaky.
`flutter build aar`
This new build command works just like `flutter build apk` or `flutter build appbundle`, but for plugin and module projects.
This PR also refactors how plugins are included in app or module projects. By building the plugins as AARs, the Android Gradle plugin is able to use Jetifier to translate support libraries into AndroidX libraries for all the plugin's native code. Thus, reducing the error rate when using AndroidX in apps.
This change also allows to build modules as AARs, so developers can take these artifacts and distribute them along with the native host app without the need of the Flutter tool. This is a requirement for add to app.
`flutter build aar` generates POM artifacts (XML files) which contain metadata about the native dependencies used by the plugin. This allows Gradle to resolve dependencies at the app level. The result of this new build command is a single build/outputs/repo, the local repository that contains all the generated AARs and POM files.
In a Flutter app project, this local repo is used by the Flutter Gradle plugin to resolve the plugin dependencies. In add to app case, the developer needs to configure the local repo and the dependency manually in `build.gradle`:
repositories {
maven {
url "<path-to-flutter-module>build/host/outputs/repo"
}
}
dependencies {
implementation("<package-name>:flutter_<build-mode>:1.0@aar") {
transitive = true
}
}
