Enhance documentation on Prefect Settings

First check

[X] I added a descriptive title to this issue.
[X] I used GitHub search to find a similar request and didn't find it 😇

Describe the issue

There is a lot of great advanced functionality enabled via settings, but many of them are not documented in a friendly way.

Describe the proposed change

Would be great to have a table of all the settings, what they do, and when one might use them. Even better would be something autodocumenting, that could parse these settings and generate the table / information we're looking for from descriptions.

Additional context

There are a lot of settings
