Create shared component for index pattern selection

[kertal]

Currently we have 3 different index pattern selection components. Lens, Discover, Graph integrated their own component. The component created for Lens should be migrated to be a shareable component.

Lens index pattern selection:

Discover index pattern selection:

Graph index pattern selection:

There is already a component like this (src/legacy/core_plugins/data/public/index_patterns/components/index_pattern_select.tsx - thanks @lizozom). We can use this ticket to track the update with the Lens popover/selectable version.

would be simple to do this as the reason for separating these no longer exists (licensing)

@flash1293 @kertal Is this something we still would see any value in doing, or should we close this issue?

[kertal]

well there are discussions around that are more advanced than this issue:

#72098
#72098 (comment)

So I do think we need this, question is, what's the best issue to track it?

[flash1293]

I still think it makes sense to unify it - I expect with more features added to data views it's going to grow in complexity

Closing since it was done with #127244
