[CP-beta]Fix Android license detection for cmdline-tools 23.0+ (#192132)

This pull request is created by [automatic cherry pick workflow](https://github.com/flutter/flutter/blob/main/docs/releases/Flutter-Cherrypick-Process.md#automatically-creates-a-cherry-pick-request)
Please fill in the form below, and a flutter domain expert will evaluate this cherry pick request.

### Issue Link:
https://github.com/flutter/flutter/issues/191487

### Impact Description:
Android SDK Command-line Tools 23.0 deprecated `sdkmanager --licenses` in favor of the new `android` CLI. When invoked, `sdkmanager --licenses` now only outputs a deprecation notice (`Warning: The --licenses option is no longer needed.`) rather than the parseable license summary `flutter doctor` previously depended on.

As a result, `flutter doctor` fails to parse license status and reports `✗ Android license status unknown.` while prompting users to run `flutter doctor --android-licenses`, which fails to resolve the issue. 

### Changelog Description:
[flutter/191487] When using Android SDK Command-line Tools 23.0+ for Android, flutter doctor incorrectly reports "Android license status unknown".

### Workaround:
1. Downgrade Android SDK Command-line Tools to version 22.0 via the Android Studio SDK Manager or CLI.
2. If licenses have already been accepted on disk in `<Android-SDK>/licenses/`, Android Gradle builds still succeed and the `flutter doctor` warning can be safely ignored (if the user knows to ignore).

### 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:
1. Ensure Android SDK Command-line Tools 23.0 is installed (verify in `$ANDROID_HOME/cmdline-tools/latest/source.properties` that `Pkg.Revision=23.0`).
2. Run `flutter doctor -v`.
3. Verify that under `Android toolchain`, it reports `• All Android licenses accepted.` instead of `✗ Android license status unknown.`
4. (Optional negative check) Temporarily rename the `$ANDROID_HOME/licenses` directory, run `flutter doctor -v`, and verify it reports `Android licenses not accepted`. Restore the directory.

Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.

Documentation

For release and other announcements, join the flutter-announce mailing list. Our documentation also tracks breaking changes across releases.

Terms of service

The Flutter tool may occasionally download resources from Google servers. By downloading or using the Flutter SDK, you agree to the Google Terms of Service: https://policies.google.com/terms

For example, when installed from GitHub (as opposed to from a prepackaged archive), the Flutter tool will download the Dart SDK from Google servers immediately when first run, as it is used to execute the flutter tool itself. This will also occur when Flutter is upgraded (e.g. by running the flutter upgrade command).

About Flutter

We think Flutter will help you create beautiful, fast apps, with a productive, extensible and open development model, whether you're targeting iOS or Android, web, Windows, macOS, Linux or embedding it as the UI toolkit for a platform of your choice.

Beautiful user experiences

We want to enable designers to deliver their full creative vision without being forced to water it down due to limitations of the underlying framework. Flutter‘s layered architecture gives you control over every pixel on the screen and its powerful compositing capabilities let you overlay and animate graphics, video, text, and controls without limitation. Flutter includes a full set of widgets that deliver pixel-perfect experiences whether you’re building for iOS (Cupertino) or other platforms (Material), along with support for customizing or creating entirely new visual components.

Fast results

Flutter is fast. It's powered by hardware-accelerated 2D graphics libraries like Skia (which underpins Chrome and Android) and Impeller. We architected Flutter to support glitch-free, jank-free graphics at the native speed of your device.

Flutter code is powered by the world-class Dart programming language, which enables compilation to 32-bit and 64-bit ARM machine code for iOS and Android, JavaScript and WebAssembly for the web, as well as Intel x64 and ARM for desktop devices.

Productive development

Flutter offers stateful hot reload, allowing you to make changes to your code and see the results instantly without restarting your app or losing its state.

Extensible and open model

Flutter works with any development tool (or none at all), and also includes editor plug-ins for both Visual Studio Code and IntelliJ / Android Studio. Flutter provides tens of thousands of packages to speed your development, regardless of your target platform. And accessing other native code is easy, with support for both FFI (on Android, on iOS, on macOS, and on Windows) as well as platform-specific APIs.

Flutter is a fully open-source project, and we welcome contributions. Information on how to get started can be found in our contributor guide.
