Adds warning to `flutter create` command that checks if detected Java version is compatible with the template AGP and template Gradle versions. If a developer is building for Android and their Java version is incompatible with either the AGP or Gradle versions that Flutter currently supports by default for new Flutter projects, then
- a warning will show noting the incompatibility and
- steps will be shown to fix the issue, the recommended option being to configure a new compatible Java version given that Flutter knows we can support the template Gradle/AGP versions and updating them manually may be risky (feedback on this approach would be greatly appreciated!)
Given that the template AGP and Gradle versions are compatible, this PR assumes that the detected Java version may only conflict with one of the template AGP or Gradle versions because:
- the minimum Java version for a given AGP version is less than the maximum Java version compatible for the minimum Gradle version required for that AGP version (too low a Java version will fail AGP compatibility test, but not Gradle compatibility).
- the maximum Java version compatible with minimum Gradle version for a given AGP version is higher than minimum Java version required for that AGP version (too high a Java version will fail Gradle compatibility test, but not AGP compatibility test).
Fixes https://github.com/flutter/flutter/issues/130515 in the sense that `flutter create foo`; `cd foo`; `flutter run` should always be successful.

We decided that redefining the default for templates was premature. We're going to go back to having "module" in experimental land again, and we'll try again when we have the feature set fully baked.
This keeps the writing of the .metadata files, and writing the template type to them, because that was a good improvement, and there are still a bunch of added tests that improve our coverage.
This renames the "module" template to the "application" template, and makes "application" the default. The existing "app" template is now deprecated.
flutter create also now recognizes the type of project in an existing directory, and is able to recreate it without having the template type explicitly specified (although you can still do that). It does this now by first looking in the .metadata file for the new project_type field, and if it doesn't find that, then it looks at the directory structure. Also, the .metadata file is now overwritten even on an existing directory so that 1) the project_type can be added to legacy projects, and 2) the version of Flutter that updated the project last is updated.
I also cleaned up a bunch of things in create_test.dart, added many more tests, and added an example test to the test/ directory in the generated output of the application template.
