Rollup merge of #63196 - RalfJung:build_helper, r=alexcrichton

build_helper: try less confusing method names

build_helper's `*_silent` methods were likely called that way because they do not print the command being run to stdout. [In the original file this all makes sense](046e6874c4 (diff-5c3d6537a43ecae03014e118a7fe3321)). But later it also gained `*_suppressed` methods and the difference between `silent` and `suppressed` is far from clear.

So rename `run` (which prints the command being run) to `run_verbose`. Then we can call the methods that just run a command and show its output but nothing extra `run` and `try_run`.

`run_verbose` (formerly `run`) is unused from what I can tell. Should I remove it?
