Roll Flutter (stable) from c197ca5199e9 to ab2912035e16 (1647 revisions) - #13625

Does the steps for [Updating-Packages-repo-for-a-stable-release.md](https://github.com/flutter/flutter/blob/main/docs/ecosystem/release/Updating-Packages-repo-for-a-stable-release.md) for the 3.50 stable release:

- Adds 3.47.9 (Dart 3.13.7) and 3.50.0 (Dart 3.14.0) to the repo tool's Flutter-to-Dart version mapping.
- Moves the legacy analysis tasks to N-1 = 3.47.9 and N-2 = 3.44.9.
- Raises the repo's minimum Flutter version to 3.44.0, and updates every package below it with `update-min-sdk --flutter-min=3.44.0`.
- Adds `NEXT` CHANGELOG entries with `update-release-info --version=next` (no version bumps, per repo policy), but only to packages whose own minimum SDK changed; packages where only an example or another unpublished pubspec changed get no entry. Packages that haven't released since the 3.47 update already had a 3.41 SDK-bump line in `NEXT`; that line is removed so each section has only one. `webview_flutter_android`'s `NEXT` section had only a stale 3.41 line (it has required 3.44 since 4.12.1), so that section is removed.
- Updates the release action to Flutter 3.50.0.

Additional adjustments needed for CI with the updated versions:

- Applies `dart fix --code=prefer_initializing_formals` across packages whose language version moved to Dart 3.12, adopting private named parameters (`this._foo`; call-site argument names and doc comment references are unchanged).
- Temporarily disables `prefer_initializing_formals` via a local `analysis_options.yaml` in `packages/pigeon/platform_tests/shared_test_plugin_code` (opted in via `packages/pigeon/ci_config.yaml`), since its Pigeon-generated files under `lib/src/generated/` trigger the lint at language version 3.12+ and cannot be edited by hand.
- Adds temporary `// ignore` / `// ignore_for_file: uri_does_not_exist_in_doc_import` comments (tracked in flutter/flutter#196406) to 20 files in `cupertino_ui`: with N-1 now at 3.47.9, `cupertino_ui` runs in legacy analysis for the first time, where `remove-dev-dependencies` strips `material_ui` and leaves its `@docImport`s unresolved. Uses `override: no changelog needed` since `cupertino_ui` only receives comment changes.

The stable pin (`.ci/flutter_stable.version`) is updated separately by the autoroller in #13625.

There's no tracking issue for this routine post-release update.

## Pre-Review Checklist

**Note**: The Flutter team is currently trialing the use of [Gemini Code Assist for GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code). Comments from the `gemini-code-assist` bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.

[^1]: Regular contributors who have demonstrated familiarity with the repository guidelines only need to comment if the PR is not auto-exempted by repo tooling.
