Dropdown - menuAppendTo is missing from docs

[mcoker]

In the dropdown component docs, we have an append menu document body example that uses menuAppendTo, but that prop is missing from the docs. I checked the select component docs and it's listed there. I'm not sure what all components support that prop but it might be good to double check the docs for those components, too.

@mcarrano we had to revert the PR that closed this. Can you reprioritize this issue please.

The product was relying on ToggleMenuBaseProps since it was publicly exposed.
