Popover Component (split usecase from Tooltip component)

[mlmoravek]

Description

The OTooltip component can currently be used as either a tooltip or a popover.
However, a popover is slightly different to a tooltip in terms of its use case.

A tooltip should only open on hover and provide additional accessibility support for devices without a mouse. Tooltips should only contain additional informative text and no interactive elements.

In contrast, a popover can be opened by clicking or through other active interactions. Unlike a tooltip, a popover can contain interactive elements and should not be closable by moving the mouse out of the popover by default. It must have different accessibility support to a tooltip and is normally closed by an active interaction event.

Why Oruga need this feature

Improve accessibility support and implement components with distinct use cases.
