Support for FFI calls with `@Native external` functions through Native assets on MacOS and iOS. This enables bundling native code without any build-system boilerplate code.

### Implementation details for MacOS and iOS.
Dylibs are bundled by (1) making them fat binaries if multiple architectures are targeted, (2) code signing these, and (3) copying them to the frameworks folder. These steps are done manual rather than via CocoaPods. CocoaPods would have done the same steps, but (a) needs the dylibs to be there before the `xcodebuild` invocation (we could trick it, by having a minimal dylib in the place and replace it during the build process, that works), and (b) can't deal with having no dylibs to be bundled (we'd have to bundle a dummy dylib or include some dummy C code in the build file).
The dylibs are build as a new target inside flutter assemble, as that is the moment we know what build-mode and architecture to target.
The mapping from asset id to dylib-path is passed in to every kernel compilation path. The interesting case is hot-restart where the initial kernel file is compiled by the "inner" flutter assemble, while after hot restart the "outer" flutter run compiled kernel file is pushed to the device. Both kernel files need to contain the mapping. The "inner" flutter assemble gets its mapping from the NativeAssets target which builds the native assets. The "outer" flutter run get its mapping from a dry-run invocation. Since this hot restart can be used for multiple target devices (`flutter run -d all`) it contains the mapping for all known targets.
### Example vs template
The PR includes a new template that uses the new native assets in a package and has an app importing that. Separate discussion in: https://github.com/flutter/flutter/issues/131209.
### Tests
This PR adds new tests to cover the various use cases.
* dev/devicelab/bin/tasks/native_assets_ios.dart
* Runs an example app with native assets in all build modes, doing hot reload and hot restart in debug mode.
* dev/devicelab/bin/tasks/native_assets_ios_simulator.dart
* Runs an example app with native assets, doing hot reload and hot restart.
* packages/flutter_tools/test/integration.shard/native_assets_test.dart
* Runs (incl hot reload/hot restart), builds, builds frameworks for iOS, MacOS and flutter-tester.
* packages/flutter_tools/test/general.shard/build_system/targets/native_assets_test.dart
* Unit tests the new Target in the backend.
* packages/flutter_tools/test/general.shard/ios/native_assets_test.dart
* packages/flutter_tools/test/general.shard/macos/native_assets_test.dart
* Unit tests the native assets being packaged on a iOS/MacOS build.
It also extends various existing tests:
* dev/devicelab/bin/tasks/module_test_ios.dart
* Exercises the add2app scenario.
* packages/flutter_tools/test/general.shard/features_test.dart
* Unit test the new feature flag.
Fixes https://github.com/flutter/flutter/issues/89683.
The changes to `getFlutterView` in `FlutterDeviceScreenshot` are the fix that was required, everything else was done to get tests running (such as re-generating some lockfiles and modifying the android manifest).
The code was all currently not unit tested, and there were no other easy examples to base these java unit tests off in flutter/flutter, so let me know if this approach to testing is wrong.
Adds the first Windows Arm64 devicelab test. The builder for this test won't be created until after this lands on master, so we can't actually test this until this is merged.
Enable Impeller benchmarks for drawAtlas/drawVertices on iOS/Metal, Android/GLES, and Android/Vulkan.
Enable impeller tessellation benchmarks on iOS/Metal and Android/Vulkan - not GLES as this is measuring backend agnostic performance.
Temporarily removes Xcode debug tests.
Xcode tests are currently failing in CI for some infra-related issues. I have a fix for it (https://github.com/flutter/flutter/pull/132318) that I confirmed worked in presubmit, but I think the logic is better suited to live in recipes. However, it's going to be a bit of a learning curve to update recipes and might take me a couple days so disabling them in the meantime.
Tracking issue to readd when ready: https://github.com/flutter/flutter/issues/132309
This PR includes the following changes. These changes only apply to iOS 17 physical devices.
| Command | Change Description | Changes to User Experience |
| ------------- | ------------- | ------------- |
| `flutter run --release` | Uses `devicectl` to install and launch application in release mode. | No change. |
| `flutter run` | Uses Xcode via automation scripting to run application in debug and profile mode. | Xcode will be opened in the background. Errors/crashes may be caught in Xcode and therefore may not show in terminal. |
| `flutter run --use-application-binary=xxxx` | Creates temporary empty Xcode project and use Xcode to run via automation scripting in debug and profile. | Xcode will be opened in the background. Errors/crashes may be caught in Xcode and therefore may not show in terminal. |
| `flutter install` | Uses `devicectl` to check installed apps, install app, uninstall app. | No change. |
| `flutter screenshot` | Will return error. | Will return error. |
Other changes include:
* Using `devicectl` to get information about the device
* Using `idevicesyslog` and Dart VM logging for device logs
Note:
Xcode automation scripting (used in `flutter run` for debug and profile) does not work in a headless (without a UI) interface. No known workaround.
Fixes https://github.com/flutter/flutter/issues/128827, https://github.com/flutter/flutter/issues/128531.
In order to avoid new tasks from not being scheduled we are not going to backfill the autoroller because it can sometimes play transactions out of order causing issues with tasks that are scheduled but not known.

Fixes:

It was observed that the tests would hit their 30 minute timeout so this PR adds another shard to reduce how many tests are run per shard to reduce test run time
`ios_app_with_extensions_test` only builds the artifact, it does not need a device to run.
This PR adds the copies of these tests to run hostonly. When the new tests pass in post submit, we should remove the old ones.
We've decided to use the `--omit-type-checks` flag for our dart2wasm benchmarks. Right now, many of the benchmark results are dominated by type checks and most of what we are actually trying to measure get drowned out in the noise.

Oriole is the Pixel 6, Panther is the Pixel 7. Panther is more available in FTL at this point.
There's less value in running this on presubmit, since those can spawn many jobs multiple times over as people push new commits to branches. Let's just run it post submit to avoid overloading the capacity of FTL.
MInor cleanup to remove the use_emulator flag as adding the virtual device is enough to signal use of an emulator.

This change:
1. re-enables the Linux packages_autoroller
2. ensures we redact the token from appearing in any logs (in local testing I realized some failure logs might still expose the token)
What actually fixed authentication however was creating and uploading a new GitHub personal access token, not this change.
It's currently failing post-submit because being marked `bringup` it is running in the try pool, which does not have permissions to access the cloud KMS. However, I ran a LED build in the prod pool that succeeded:
3a8f128c35/+/build.proto?server=chromium-swarm.appspot.com
Even after updating the account (and the cloudKMS GitHub token), when
the bot tries to push to
https://github.com/flutter-pub-roller-bot/flutter, it gets a 403, which
probably means authentication failed. I will have to investigate next
week.

This enables benchmarks for the Skwasm renderer, compiled with
dart2wasm.
Platform views aren't supported in Skwasm yet, so we are skipping those
benchmarks for now.
