Consolidate tooltip components

[dmfalke]

We can start with moving this component to this repo.

A related follow-up task will be to convert all existing tooltips to use this one.

@jernestmyers suggests moving to a newer MUI version - might be better placement mechanism

Should one of these issues be closed?

Note that this issue includes a reference to improving the performance of tooltips when we have a large list of elements with tooltips: #127 (comment)

ETA I'm not suggesting that we address this at the same time as consolidation. I just want to keep the idea in our heads.
