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.
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.

Because the cost of type checks dominate our dart2wasm benchmarks, we've
decided to pass `--omit-type-checks` for now.
This was previously reverted because the skwasm benchmarks were broken
in general for a separate reason, and my getting rid of `bringup: true`
broke the tree. I ended up fixing the benchmarks and getting rid of
`bringup: true` in a separate commit, so this just adds the flag only.
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.
Adding debugging for https://github.com/flutter/flutter/issues/129836.
Takes a screenshot when startup test takes too long (10 minutes).
Also, removes some old debugging and add new debugging message.
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.
By default, the browser fuzzes the timer APIs such that they have a granularity of approximately 100 microseconds (this is due to Spectre mitigation techniques). However, many of the thing we are trying to measure actually have a much finer granularity than 100 microseconds. As a result, many of our benchmarks are extremely noisy and don't provide accurate data.
By serving the initial script files with the `Cross-Origin-Opener-Policy: same-origin` and `Cross-Origin-Embedder-Policy: require-corp` HTTP headers, the browser runs the benchmarks in a `crossOriginIsolated` context, which restores the fine granularity of APIs such as `performance.now()` to microsecond precision.
Also, we were considering anything an outlier that was more than one standard deviation away from the mean. In a normal distribution, that means we are only capturing 68% of the data and the rest are considered outliers. This is not ideal. Doing two standard deviations away captures 95% of the data, and the outliers are in the remaining 5%, which seems much more reasonable.
I think the flake is due to setclipboard or semantics update race condition. I migrated the test to use integration test package which relies less on timing

* Add Linux unit tests to plugin template
Adds an example native unit test to the plugin template for Linux,
matching the structure we use for our 1P plugin unit tests. Once these
have been added for all platforms+languages, they will be documented on
a new plugin development page to explain their use.
While ideally we would adjust the engine APIs first to allow for testing
the method call handler directly, it's unclear when we will have time
for that work, and for a complex plugin most of the testing wouldn't be
at that layer anyway, so having the structure in place with the
limitations documented is still a significant improvement over having
nothing in the template.
