feat(flutter_tools): add IntOptionDescriptor and DefaultedIntOptionDescriptor - #192455

…lutter#193323)

Migrate `BuildLinuxCommand` (`build linux`) and `BuildWindowsCommand`
(`build windows`) to typed `OptionDescriptor`s and `OptionBundle`s
(following flutter#191018, flutter#191510, flutter#191760, flutter#192307, flutter#192455, flutter#192524, and
flutter#192818):

- Add `DesktopBuildOptionsBundle` in `common_options.dart`,
encapsulating `CommonBuildOptionsBundle`, `BuildModeOptionsBundle`,
`DartCompileOptionsBundle`, `BuildInfoOptions.flavor`, `splitDebugInfo`,
`obfuscate`, `extraFrontEndOptions`, `extraGenSnapshotOptions`,
`performanceMeasurementFile`, `analyzeSize`, `codeSizeDirectory`,
`trackWidgetCreation`, and `configOnly`.
- Migrate `BuildLinuxCommand` (`build_linux.dart`) to
`DesktopBuildOptionsBundle`,
`DefaultedEnumOptionDescriptor<TargetPlatform>`
(`_targetPlatformOption`), and `DefaultedStringOptionDescriptor`
(`_targetSysroot`), replacing untyped `boolArg('config-only')`,
`stringArg('target-platform')!`, and `stringArg('target-sysroot')!`
queries.
- Migrate `BuildWindowsCommand` (`build_windows.dart`) to
`DesktopBuildOptionsBundle` and
`getValue(DesktopBuildOptionsBundle.configOnly)`.
- Delete the obsolete `FlutterCommand.addCommonDesktopBuildOptions`
helper method from `flutter_command.dart` (no remaining callers in
`flutter_tools`).

…lutter#194017)

### Rationale

`FlutterTestRunner.runTests` accepted 33 loose parameters (duplicating
23 of them on `runTestsBySpawningLightweightEngines` alongside
duplicated `package:test` CLI argument lists), and
`DriverService.startTest` accepted 12 loose parameters fed by untyped
`boolArg` / `stringArg` / regex splitting in `TestCommand` and
`DriveCommand`. Following flutter#191018, flutter#191510, flutter#191760, flutter#192307, flutter#192455,
flutter#192524, flutter#192818, and flutter#193323, this change introduces immutable
service-layer specification objects and migrates `TestCommand` and
`DriveCommand` to typed `OptionDescriptor`s.

### Summary of Changes

- Introduce `@immutable class TestFilterSpecification` and `@immutable
class TestExecutionSpecification` (with `toPackageTestArgs()`) in
`test/runner.dart`, shrinking `FlutterTestRunner.runTests` from 33
parameters to 3 (`testWrapper`, `testFiles`, `spec`) and
`runTestsBySpawningLightweightEngines` from 25 parameters to 2
(`testFiles`, `spec`).
- Migrate `TestCommand` (`commands/test.dart`) from inline `argParser`
registrations and untyped `boolArg`/`stringArg`/`stringsArg` queries to
private typed `OptionDescriptor` constants (`argParser.addDescriptors` +
`getValue` / `wasParsed`), and update `bin/fuchsia_tester.dart`.
- Introduce `@immutable class DriveTestSpecification` (with
`parseBrowserDimension`) in `drive/drive_service.dart`, shrinking
`DriverService.startTest` (and `FlutterDriverService` /
`WebDriverService`) from 12 parameters to 2 (`testFile`, `spec`).
- Migrate `DriveCommand` (`commands/drive.dart`) from inline
registrations and ad-hoc string/int/enum parsing to private typed
`OptionDescriptor` constants (`IntOptionDescriptor`,
`DefaultedEnumOptionDescriptor<Browser>`, etc.) and
`DriveTestSpecification`.
- Update unit tests across `test_test.dart`, `drive_test.dart`,
`drive_service_test.dart`, and `web_driver_service_test.dart`.

…fig to AndroidBuildInfo (flutter#194016)

### Rationale

`BuildInfo` is the cross-platform build configuration passed across
Android, iOS, Web, Desktop, and Fuchsia targets, yet it carried 6 loose
Android/Gradle fields (`androidProjectArgs`,
`androidGradleProjectCacheDir`, `androidGradleDaemon`,
`androidSkipBuildDependencyValidation`, `androidEnableHcpp`,
`explicitAndroidEnableHcpp`) and the Gradle `-P` flag serializer
`toGradleConfig()`. Following flutter#191018, flutter#191510, flutter#191760, flutter#192307,
flutter#192455, flutter#192524, flutter#192818, and flutter#193323, this change encapsulates those
fields into `AndroidGradleConfig` and moves `toGradleConfig()` onto
`AndroidBuildInfo` where all production callers already operate.

### Summary of Changes

- Introduce `@immutable class AndroidGradleConfig` in `build_info.dart`
and replace the 6 loose `android*` parameters on `BuildInfo` and
`BuildInfo.copyWith` with `androidGradleConfig` (shrinking `BuildInfo`'s
constructor from 28 to 23 parameters while preserving
`AndroidDevice.startApp` forwarding during `flutter run`).
- Move `toGradleConfig()` off `BuildInfo` onto `AndroidBuildInfo` (with
zero `@deprecated` forwarders) and add `gradleDaemon` and
`skipBuildDependencyValidation` convenience getters on
`AndroidBuildInfo`.
- Update `FlutterCommand.getBuildInfo()` in `flutter_command.dart` to
construct `AndroidGradleConfig`.
- Update `buildGradleApp`, `buildGradleAar`, and
`_checkJavaAndGradleCompatibility` in `gradle.dart` to read Gradle
configuration via `AndroidBuildInfo`.
- Update unit tests across `build_info_test.dart`,
`flutter_command_test.dart`, `android_gradle_builder_test.dart`, and
`build_aar_test.dart`.

```

### Verification

- Executed `dart analyze --fatal-infos` on `packages/flutter_tools` with
0 issues.
- Executed `dart test` across `build_info_test.dart`,
`flutter_command_test.dart`, `android_gradle_builder_test.dart`, and
`build_aar_test.dart` (`160/160` passing).
