…0858)

flutter#190878 added `--preset` / `-P` support to `flutter test`. This PR adds
real-command integration coverage for that behavior in both the standard
and experimental faster test runners.

The tests exercise the short and long flag forms, an undefined preset,
composition with `--plain-name`, and a two-file
`--experimental-faster-testing` invocation.

Related to flutter#189191.
