Run framework smoke tests in parallel

By default, flutter/dart test will only use half of the available
cores. This builder runs on an 8 core machine (and would benefit
from a larger machine), so this CL bumps the concurrency level
up to 8. Unfortunately, I'm only able to measure a 3-ish minute
improvement in the execution time of the step.

Flutter LUCI Recipes

This repository contains Flutter's LUCI recipes. For the LUCI infrastructure config, see flutter/infra. Builds can be found in the Flutter Dashboard.

Supported repositories roll their .ci.yaml into flutter/infra, which updates what properties builds have. For example, flutter config specifies various dependencies the different tests require, which are then used by the flutter_deps recipe_module No modifications to flutter/infra are required to work on the recipes.
