Additionally, the math in the methods is reduced compared to the general
case math based on known input conditions.

`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
    }
}

This reverts commit 11460b83.

Plus:

- Resume the app being run after expression has been evaluated to prevent the test run being forcefully terminated because it didn't end
- Skip non-JSON when waiting for JSON (eg. when running in verbose mode for debugging locally)
- Pass defaultTimeout in waitForJson (otherwise the assert in _timeoutWithMessages fails when it's not provided)

Closes https://github.com/flutter/flutter/issues/26518 (the original reason for skip was fixed in https://github.com/dart-lang/sdk/issues/34224).

Made the Flutter Gallery use the new ThemeMode property so that it can
use the system's dark/light mode setting by default.
