Allow component properties to be categorized

I should note that Lauri asked me in Slack to create this issue :)

"category" as a term is the worst possible choice given 📌 Define built-in components and categorization for components Postponed in XB and ✨ ComponentPluginManager must implement CategorizingPluginManagerInterface Active in Drupal core — if both the SDC itself has a category and every SDC prop does too, then what does "category" even mean anymore?! 😅

Also, to not violate @lauriii's product requirement 3. Real-time page preview's spirit ("no XB-specific metadata or logic in SDCs"), this will need to become part of SDC itself, so it should be added to 📌 [SPIKE] Comprehensive plan for integrating with SDC Active .

Ideally, these groupings can open/close and we can also define which of these groupings are open by default. For example, we may want to close the "Styling" and "Advanced" props by default so as to not overwhelm the user.

This sounds very similar to, but different from in 📌 [SPIKE] Comprehensive plan for integrating with SDC Active .

📌 Define built-in components and categorization for components Postponed is in.

@kristen pol Any thoughts from you on #3 until @lauriii gets a chance to respond? 😊
