dart dev/tools/bin/generate_gradle_lockfiles.dart` after
dev/tools/bin/generate_gradle_lockfiles.dart to bump the versions of
kotlin.

Verified example test that cause revert was passing by running the
following
- `../../bin/cache/dart-sdk/bin/dart bin/test_runner.dart test -t
run_debug_test_android.dart` from `dev/devicelab`
- `../../bin/cache/dart-sdk/bin/dart bin/test_runner.dart test -t
run_release_test` from `dev/devicelab`
- `SHARD=android_engine_vulkan_tests bin/cache/dart-sdk/bin/dart
dev/bots/test.dart` from root with an android emulator. Hard to actually
verify because the emulator is closed as part of the tests but no
failures were from failures to compile.

This change reverts the following previous change:
I recently noticed the following log when building an app in verbose mode:
```
This Android Gradle plugin (8.1.0) was tested up to compileSdk = 33 (and compileSdkPreview = "UpsideDownCakePrivacySandbox").
You are strongly encouraged to update your project to use a newer
Android Gradle plugin that has been tested with compileSdk = 35.
```
It looks like AGP would like us to use a newer AGP version if we want to use compileSdk 35 (which we do). This pr upgrades the tests, in advance of updating the templates.

Updates `compileSdk`, `targetSdk`, and `ndk` versions (former 2 to latest, latter to the version of the ndk we are hosting on CIPD).
Summary of changes:
- Updates mentioned template values
- `compileSdk` 35 requires AGP 8.0+, so updated to 8.1 in many places.
- This also necessitated Gradle upgrades in most places
- This also necessitated moving the `package` xml attribute to the AGP `namespace` field in a couple places (test + template).
- Some tests use the output of `flutter create` but then use intentionally lower AGP versions. [I downgraded the `compileSdk` in these tests.](fee34fd61a)
- [Stopped lockfile generation](82324a2570) script from hitting the `hello_world` example because it uses `.kts` gradle files.
- One test needed [some Gradle options we had already added to templates](6aa187b4b6).

PR to pave the way for https://github.com/flutter/engine/pull/53001 to re-land
Summary:
- Enforces use of Kotlin >= `1.7.0` (please see below note)
- Fixes ci failures that prevented the above PR from landing.
Details:
Because it landed initially, we are able to fake the roll in this PR to fix all the tests ([see my comment](https://github.com/flutter/flutter/pull/149204#discussion_r1617924772)).
Fixes all the tests that failed:
1. `module_test` failing on multiple platforms (3/9 of the failures).
Failure is
```
> Android resource linking failed
ERROR:/b/s/w/ir/x/t/flutter_module_test.KECMXW/hello/.android/plugins_build_output/device_info/intermediates/merged_res/release/values/values.xml:194: AAPT: error: resource android:attr/lStar not found.
```
This is a rather unhelpful error message but some [folks online suggest](https://stackoverflow.com/a/69050529) that upgrading your `compileSdk` version fixes this.
These resolve when I remove the dependency on the long discontinued [package_info](https://pub.dev/packages/package_info) and [device_info](https://pub.dev/packages/device_info) packages, perhaps because they are transitively pulling in low `compileSdk` versions? This is unclear to me.
2. `module_custom_host_app_name_test` was failing for the same reason (another 3/9, or cumulative 6/9).
3. `tool_integration_tests_3_4` was a flake ð (7/9)
4. `framework_tests_slow` needed a newer version of the Kotlin Gradle plugin (the flutter tool tells us this, so I just upgraded as suggested) and it resolved (8/9)
5.`android_preview_tool_integration_tests` needed newer AGP and KGP versions. I also refactored the tests, and bumped our error versions, fixing https://github.com/flutter/flutter/issues/142653.
**Note that the bump to KGP is not in line with our policy** - we didn't warn for `1.5.0-1.6.x` for a release (or at all) before dropping support. But I think it might still be justified:
- The bump to our androidx libraries unblocks ongoing Scribe work, and also includes a fix for a [memory leak](https://github.com/flutter/flutter/issues/129307#issuecomment-1601636959) and a [crash on folding phones](https://github.com/flutter/flutter/issues/114868#issuecomment-2133226962), among many other bug fixes.
- Gradle [doesn't test on half of that range](https://docs.gradle.org/current/userguide/compatibility.html#kotlin), and so we implicitly can't claim to support it either. More generally, our Java and Kotlin support ranges should probably strictly fall within what Gradle tests.
This PR updates almost* all Gradle buildscripts in the Flutter repo the `example` and `dev` (in particular, in `dev/integration_tests` and in `dev/benchmarks`) directories to apply Flutter's Gradle plugins using the declarative `plugins {}` block.
*almost, because:
- add-to-app (aka hybrid) apps are not migrated (related https://github.com/flutter/flutter/issues/138756)
- apps that purposefully use build files to ensure backward compatibility (e.g. [`gradle_deprecated_settings`](https://github.com/flutter/flutter/tree/3.16.0/dev/integration_tests/gradle_deprecated_settings))
