Support marking some metrics as "main/important"

As the number of metrics is growing, we need a way to clarify the UI and only show the important one first and have a way to show all metrics separately.

Thoughts about the current metrics:

• When I'm looking at front-end metrics, I ignore the editor metrics and vice versa. It feels these are two different sets that I don't need to see together. Are they different "projects"? Can they be grouped (shown/hidden) using tabs?

• For front-end metrics, there are different "scenarios". At the moment, we are tracking the times for the homepage of a site, but we could add new metrics for the single post template. Unlike the comment before (front-end vs editor), for these "scenarios", it'd be valuable to look at them all together. Like a table, where rows are the metrics and columns the scenario, so to speak.

Want to spin up an issue about this, I think we need both.

For instance, If I want a big picture about Gutenberg, I'd like to see: "type", "first block" and "LCP" personally.

Another idea: the cards can be hidden and rearranged by the user. That way, I can construct my own dashboard. However, this doesn't solve the fact that front-end metrics for different views (homepage vs single post) would be the same.
