…#189229)

I raised the warn and error version in this PR:
flutter#189109. The dependencies used by
`flutter_engine_group_performance` were not updated as a part of that
PR. I missed that update earlier, and I'm guessing that
`flutter_engine_group_performance` is post-submit test.

Fixes flutter#189228

This was a manual cherry pick of #189109 and of #189229.

### Issue Link:
What is the link to the issue this cherry-pick is addressing?

#189228

### Impact Description:
What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)?
Does it impact development (ex. flutter doctor crashes when Android Studio is installed),
or the shipping of production apps (the app crashes on launch).
This information is for domain experts and release engineers to understand the consequences of saying yes or no to the cherry pick.

This affects all Flutter Android apps and add-to-app integrations below the new warn and error version thresholds. Apps below the warn version will successfully build with warning logs urging an upgrade. Apps below the error version will fail to build and receive logs to upgrade.

New Warn Version
AGP: 9.0.1
Gradle: 9.1.0
KGP: 2.3.20

New Error Version
AGP: 8.11.1
Gradle: 8.14
KGP: 2.2.20

### Changelog Description:
Explain this cherry pick:
* In one line that is accessible to most Flutter developers.
* That describes the state prior to the fix.
* That includes which platforms are impacted.
See [best practices](https://github.com/flutter/flutter/blob/main/docs/releases/Hotfix-Documentation-Best-Practices.md) for examples.

< Replace with changelog description here >
[flutter/189383](#186100): When building Flutter Android apps and add-to-app modules using AGP < 9, the tool does not prompt developers to upgrade to AGP 9+ or log Built-in Kotlin migration warnings.

### Workaround:
Is there a workaround for this issue?

This change must be made. More develoeprs should upgrade to AGP 9+ to receive Built-in Kotlin migration warnings. To urge more developers to migrate to AGP 9+, we must raise the warn version to AGP 9+ to urge a larger chunk of our developers to migrate to AGP 9+. This must be done in this release because we don't have many Flutter releases left before AGP 10 releases.

### Risk:
What is the risk level of this cherry-pick?

### Test Coverage:
Are you confident that your fix is well-tested by automated tests?

### Validation Steps:
What are the steps to validate that this fix works?
To validate the new warn version:
- `flutter create` a new app
- change versions to just below the warn version AGP: 9.0.1, Gradle: 9.1.0 KGP: 2.3.20 in settings.gradle.kts
- `flutter build apk` and the build is successful but you will see logs urging you to upgrade.
- change versions to the warn version GP: 9.0.1, Gradle: 9.1.0 KGP: 2.3.20 in settings.gradle.kts
-`flutter build apk` and the build is successful and you will see no logs

To validate the new error version:
- change versions to just below the error version AGP: 8.11.1, Gradle: 8.14 KGP: 2.2.20 in settings.gradle.kts
- `flutter build apk` and the build will fail and you will see logs urging you to upgrade.
- change versions to the error version  AGP: 8.11.1, Gradle: 8.14 KGP: 2.2.20 in settings.gradle.kts
-`flutter build apk` and the build is successful and you will see no logs
