Addon-docs: Generalize DocsPage prop tables

[shilman]

Storybook's prop tables were written with React in mind, which only has the concept of props.

• Vue Addon-docs: DocsPage for Vue #6663 has the additional concept of events & slots
• Angular Addon-docs: DocsPage for Angular #6664 similarly has other types of props (outputs?)

We should generalize DocsPage to support these different component inputs/outputs.

Just to add additional use-case ideas and make the need explicit, Web Components (which I have been using through the html support in Storybook) might want to document:

• Props
• Attributes (often overlapping with Props, but not always)
• Slots
• Events
• CSS variables

You can get an idea of how this is being used right now here: #4600 (comment)

For Vue (dunno about Angular or other frameworks) it would also be interesting to support methods. E.g. https://buefy.org/documentation/collapse#api-view
