Port our microbenchmarks to the new world (#4121)

Our microbenchmarks now run on real devices.

# microbenchmarks
To run these benchmarks on a device:
```
flutter run --release -t lib/gestures/velocity_tracker_data.dart
flutter run --release -t lib/stocks/animation_bench.dart
flutter run --release -t lib/stocks/build_bench.dart
flutter run --release -t lib/stocks/layout_bench.dart
```
The results should be in the device logs.

# Benchmarks
This directory (and its sub-directories) contain benchmarks for
Flutter. The reporting format for benchmarks is not standardized yet,
so benchmarks here are typically run by hand. To run a benchmark:
1. Build `sky_shell` for Linux Release using the instructions in the
[Engine repository](https://github.com/flutter/engine).
2. Run `pub get` in the `packages/flutter` directory.
3. Run the benchmarks by running the following command from the root
of the flutter repository. Replace `stocks/layout_bench.dart` with
the path to whichever benchmark you want to run. If you didn't
build the engine in the recommended place, then also update the
path accordingly. If you made changes to sky_services, you'll also
need to update the `pubspec.yaml` file to point to that using a
dependency_override.
```
