Is your feature request related to a problem? Please describe.
Currently the only way to have a tooltip is through adding the class d-tooltip and data attribute data-tooltip. This created a :before element which isn't great for accessibility and we can't control as easily.

Describe the solution you'd like
Additionally we would like to see a tooltip component that can be called as an element rather than :before. The HTML could look like this.

<span class="d-tooltip-element">This is a tooltip</span>

Additional context
Additionally all other modifier like position and size would work for this new element.
