Skip packages which are up to date in vp update -g #1477

Description

If we run vp update -g, the current Vite+ will reinstall all the installed packages, no matter whether it is up to date, which makes update process slow.

Suggested solution

We can follow other pm's behavior like pnpm / npm, which needs Vite+ compares user's installed version with the latest version on registry, and only reinstall ones which is needed to update. We can't delegate it to npm install -g like #1476 as we use different prefixes for different packages.

Since vp can record the Node version used to install the package, whether to reinstall when node version changes may become a topic need to discuss.

Alternative

No response

Additional context

Maybe it is partially related #1476, implementing this after finishing #1476 can make work much simpler
