Show watchers in its own section

[jessegilbride]

It would be nice to see a section (like: props, setup, event listeners) for a component that gives some detail about any watcher(s) that exists. If nothing else, just showing what it is watching.

I realize that assigning the watcher to a (const) variable causes it to show up in the setup section, but that's not what I'm talking about. Plus, doing that doesn't provide any useful information.
