This adds a macrobenchmark representative of a real world application that uses SVG icons. The scenario of rasterizing complex paths that don't change over time does not seem to be covered by any other macrobenchmark and shows a significantly slower impeller performance compared to skia.
It's actually bit problematic to measure this because on A15 the CPU load with impeller is high enough to trigger CPU frequency change. So in order to get consistent reading I had to add a spinning background thread that would keep the CPU at highest frequency.
```objc
[NSThread detachNewThreadWithBlock:^{
while (true) {
pthread_yield_np();
}
}];
```
```bash
flutter drive --profile --local-engine=ios_profile -t test_driver/run_app.dart --driver test_driver/path_tessellation_static_perf_test.dart
```

* Adding the `GeometryPainter` seems to have triggered the complexity threshold for raster cache.
