Motivation and Context

Closes #361

Description

I have added a button to the popups of Components and Subsystems in a Component diagram, and to the popups of Components and Nodes in a Deployment diagram, which toggles the visibility of the stereotype.

Steps for Testing

1. Create a component/deployment diagram
2. Add a new component/subsystem/node
3. Open the popup of the newly added element by clicking on it and then on the pencil icon
4. Click on the stereotype visibility toggle button
5. Assert that the button works as expected

I will try to clarify my changes

• components/controls/icon: I added icons for the toggle button in this directory
• stereotype-toggle.tsx: File for the new toggle button
• packages/common/uml-component: I added a popup for the Component and made sure stereotype visibility is adjusted by the toggle (both in Deployment and Component diagram, as this is in the common directory)
• popups.ts: Registered new popups accordingly
• packages/uml-component-diagram: Analogue to changes in packages/common/uml-component
• packages/uml-deployment-diagram: Analogue to changes in packages/common/uml-component
• typints.ts: Adjusted types accordingly
• tests: Updated snapshots
