Rollup merge of #128874 - Kobzol:cmd-verbose-logging, r=onur-ozkan

Disable verbose bootstrap command failure logging by default

One of my recent bootstrap command refactoring PRs enabled verbose logging of command failures by default. While this is great for debugging bootstrap, in many situations it's just too verbose and prevents the user from seeing the actual printed stdout/stderr, which usually contains much more useful information.

This PR reverts that logic, and only prints a detailed error when `-v` is passed to bootstrap.
