Show perf issues in VS Code (desktop/browser)

[loujaybee]

For JetBrains we have:

• Integrate with JetBrains backend control center #10580

For CLI we have:

• https://www.gitpod.io/docs/command-line-interface#top

This issue is to implement similar perf functionality directly into VS Code.

Also useful in future with configurable workspace classes:

• Epic: Two Workspace Classes on SaaS #8261

Relates to:

• In-workspace class upgrade #11042
