Adds a Flutter Driver test under android_engine_test that drives
`SystemChrome.setEnabledSystemUIMode` through transition pairs and
asserts the resulting decor-view `systemUiVisibility` flags via a new
`get_system_ui_visibility` method on `native_driver`.

The regression-named test reproduces the
`immersiveSticky -> edgeToEdge` cell from flutter#186723 / fixed in flutter#187207:
without the fix, FLAG_FULLSCREEN and FLAG_HIDE_NAVIGATION from the
prior immersiveSticky call persist on the decor view, leaving the
system bars hidden under edgeToEdge.

Tests skip on API < 29 since edgeToEdge requires API 29+.

## Summary

Adds a Flutter Driver integration test under
`dev/integration_tests/android_engine_test/` covering `SystemUiMode`
transitions on Android. The test exposes a `requestData` handler that
applies modes via `SystemChrome.setEnabledSystemUIMode` and reads the
resulting decor-view `systemUiVisibility` flags via a new
`get_system_ui_visibility` method on the existing `native_driver` method
channel.

Closes flutter#187265.

## Why

flutter#186723 was a P1 regression introduced by flutter#183072 and fixed by flutter#187207.
The Mockito-based `PlatformPluginTest` unit tests verify which APIs are
called on a mocked `Window`/`View` but cannot observe residual
`decorView` state that bleeds across mode switches — which is the exact
bug class the regression was. A device-level integration test closes
that gap.

## What the tests cover

| Transition | Assertion |
|------------|-----------|
| `immersiveSticky → edgeToEdge` (regression case for flutter#186723) |
`FLAG_FULLSCREEN` and `FLAG_HIDE_NAVIGATION` are cleared |
| `immersive → edgeToEdge` | Same |
| `leanBack → edgeToEdge` | Same |
| `edgeToEdge → immersive` | `IMMERSIVE \| FULLSCREEN \|
HIDE_NAVIGATION` set |
| `edgeToEdge → immersiveSticky` | `IMMERSIVE_STICKY \| FULLSCREEN \|
HIDE_NAVIGATION` set |
| `edgeToEdge → leanBack` | `FULLSCREEN \| HIDE_NAVIGATION` set, no
immersive flags |

All tests skip on API < 29 since `edgeToEdge` requires Android 10+.

## Files

- New: `lib/system_ui_mode_transitions_main.dart` — Flutter Driver
entrypoint with mode-applying handler.
- New: `test_driver/system_ui_mode_transitions_main_test.dart` —
assertion suite.
- Modified: `NativeDriverSupportPlugin.kt` — adds
`get_system_ui_visibility` method that returns the decor view's
`systemUiVisibility` int. Reading the deprecated field is the most
direct signal of the regression class (flutter#186723 was specifically about
flag bleed-through on this field).
- Modified: `README.md` — adds the new entrypoint to the test list.

CI auto-discovery is via
`Glob('dev/integration_tests/android_engine_test/lib/**_main.dart')` in
`dev/bots/suite_runners/run_android_engine_tests.dart` — no separate
registration needed.

## Notes for reviewers

- Marked as draft because I do not have a local Android emulator set up
— `flutter analyze` is clean but I have not run the test end-to-end. CI
is the source of truth.
- The reason for reading the deprecated `systemUiVisibility` field on
the native side (rather than `WindowInsetsCompat.isVisible(...)`) is
that the regression was specifically about bit flags persisting on the
decor view; the deprecated read gives a deterministic,
version-independent signal. The production code still migrates to
non-deprecated APIs for *setting* state per flutter#183072.
- `SystemUiMode.manual` is out of scope here (different API surface —
takes a `List<SystemUiOverlay>`) and can follow up.

…mode (flutter#187207)

Resets system UI visibility flags before setting edge-to-edge mode if
requested.

System UI visibility flags will be set if the developer requests a
non-edge-to-edge `SystemUiMode`, which can (and does in practice)
conflict with [laying out a window
edge-to-edge](https://developer.android.com/develop/ui/views/layout/edge-to-edge-manually#lay-out-in-full-screen).
This is why [the
docs](https://developer.android.com/reference/androidx/core/view/WindowCompat#setDecorFitsSystemWindows(android.view.Window,boolean))
warn against setting system UI visibility flags altogether; see
flutter#133074 for details.

Fixes flutter#186723.
