…`dart test` (#11056)

This PR reorganizes the tests in mustache_template such that CI can run them, per the second option proposed in flutter/flutter#174721. The changes include a script to pull mustache specifications from the mustache repository and note the time/date and commit hash of that action, along with documentation of the above and the new test structure laid out below.

The former `all.dart` (which called three `main` functions in three test files) is now `mustache_test.dart`, and the former `mustache_test.dart` (which contained handwritten tests) is now `feature_test.dart`. The `mustache_specs.dart` file is now solely responsible for generating the tests in `mustache_test.dart` from the mustache specs, and no longer has a `main` of its own.

As this implementation doesn't support two of the optional mustache specs (inheritance and dynamic names, which were added to the mustache repo in the early 2020s, while the original mustache_template package was written in the mid-2010s), this PR also adds an UNSUPPORTED_SPECS constant in `mustache_test.dart` that skips generation of tests from those spec files.

(Separately, I'm working on an implementation of the inheritance spec, so it seemed better to pull all the specification files and selectively disable the unsupported ones.)

Replaces the Java Pigeon generator with the Kotlin Pigeon generator, and adjusts the project accordingly:
- Adds Kotlin build setings to Gradle.
- Updates API signatures for Kotlin/Java differences.
- Adds generic Java/Kotlin compat shim to create Result objects from Java, since those haven't been added to the Pigeon generator yet.
- Updates tests to use constructors instead of builders, since the Kotlin generator doesn't create builders.
- Updates tests to use a Java/Kotlin compat shim to read Kotlin Result values, instead of mocking the Java Pigeon response object.

…Exit (#11241)

`GoRouter.pop()` unconditionally called `restore()` after `routerDelegate.pop()`. When the route has `onExit`, the pop is deferred to a microtask, so `restore()` was called with the pre-pop configuration. This caused async redirects to overwrite
  the post-pop state, making the popped route reappear.

  Fixed by comparing `currentConfiguration` identity before and after pop. `restore()` is only called when the configuration was actually updated (synchronous pop).

Fixes flutter/flutter#174525 flutter/flutter#180002

Updates the Java formatter from 1.3 to 1.28, which is the latest version of the formatter that can be run with Java 17. Version 1.3 doesn't understand newer Java syntax that we could be using in plugins now that they all require Java 17, such as pattern expressions and switch expressions.

The changes outside of script/tool/ ware made by:
- Running the repo tool `format` command with the new version.
- Asking Gemini to fix up some bad comment wrapping in the autoformat changes (committed as a separate commit, for ease of reviewing). The new formatter enforces line length limits on comments, but doesn't re-wrap later lines after adding breaks, resulting in some comments like:
  ```java
  // Some long comment whose first line was slightly too
  // long
  // and then a bit more.
  ```

Replaces the Java Pigeon generator with the Kotlin Pigeon generator, and adjusts the project accordingly:
- Adds Kotlin build setings to Gradle.
- Updates API signatures and number handling for Kotlin/Java generator differences.
- Adds generic Java/Kotlin compat shim to create Result objects from Java, since those haven't been added to the Pigeon generator yet.
- Updates tests to use constructors instead of builders, since the Kotlin generator doesn't create builders.
  - In two cases where replacing the builder pattern would have required major changes, I instead pulled the builders from the old Java generation into the test files.
- Updates tests to use a Java/Kotlin compat shim to read Kotlin Result values, instead of mocking the Java Pigeon response object.

Part of flutter/flutter#158287
