Move verbose to environment.verbose, pass to ninja --verbose if…

… provided. (#52619)

Closes flutter/flutter#147894.

While doing this PR I realized we were basically passing `(bool verbose, Envrionment)` as a tuple around, so I just moved the concept _into_ `Environment` directly, and made the necessary code changes across the tool and tests.

To clarify, this does _not_ mimic the output of `ninja --verbose` _today_, because we also don't stream the output directly, and instead do terminal magic. Combined with a hypothetical fix for flutter/flutter#147903, this would work exactly the same as before.
