Consider replacing d3 popover/tooltip code with native Popovers

[bhousel]

Since April 2024, Popover API is supported in all evergreen browsers. We can probably replace a lot of our complex d3 code for drawing tooltips and popovers with much simpler code that works across browsers. see: https://developer.mozilla.org/en-US/docs/Web/API/Popover_API

Have we noticed issues with tooltips and other popovers across different browsers @bhousel?

Not really - this is more about clearing away tech debt.
