main: Add verbose option

We often ask ourselves: Which renderer and which backend was in use? Which GL extensions were detected. wlroots prints this on startup at log level info but it is very noisy and glib doesn't print info by default (but message), so add an option -v we can add to phosh-session but not use when people use phoc for nested testing, etc.

@arun-mani-j another "last minute" change for 0.45 but as we require a lockdep upgrade in this release it would make sense add it now so we can change phosh-session to use it for 0.45 too.

The bulk of changes in uncrustify which should be quick to review with git log -w.
