[Enhancement] Support vertically larger menus and dropdowns

[Jonaythaz]

• I have written a good issue

Describe the enhancement

Like how you can provide a custom minWidth, I would like to also be able to provide a custom maxHeight.

Describe the solution you'd like

I imagine it would work the same way as minWidth does today, although I would like to also be able to provide values other than numbers, like 85vh.

Have you considered any alternatives?

Are there any additional context?

@Jonaythaz could you, in a little more detail (e.g. screenshots), explain why you need to be able to specify maxHeight in such detail?
The menu implements roughly the same functionality as the dropdown, so making them behave differently should be done with some care.

[RasmusKjeldgaard]

Had a clarifying talk with @Jonaythaz and turns out this requirement stems from a desire to show more items in the menu than is currently allowed by the menus internally configured max-height.

So this is probably better framed as a "use available space" kind of setting on menu and dropdown, so consumers will not have to set custom heights and possibly use inconsistent sizing throughout apps. Renamed the issue accordingly.

One way this could work is to have a mode where the popover just grows to fit all available space, no matter what. That seems like the approach used in e.g. react-aria menu, where it grows to within some small distance of the viewport edge to load as many items as possible: https://react-aria.adobe.com/Menu#asynchronous-loading
