Add support for setup steps in flutter customer tests (#135726)
This PR adds support for adding `setup` steps that must be run before the `update` steps in Flutter customer tests.

```
setup=./generate_my_mocks.sh
update=.
test= ...
```

This PR also cleans up the `CustomerTest` class in the spirit of yak-shaving and making the code more robust.

This directory contains tools and resources that the Flutter team uses during the development of the framework. The tools in this directory should not be necessary for developing Flutter applications, though of course, they may be interesting if you are curious.

The tests in this directory are run in the framework_tests_misc-* shards.
