Dropdown button tooltip

Summary

Now as far as I know, there are only 2 ways to setup a tooltip for a Dropdown component:
1.- Tooltip contained in the Dropdown label:

        <Dropdown
          size="sm"
          label={
            <Tooltip
              content="Tooltip text"
              placement="bottom">
              Dropdown button text
            </Tooltip>
          }>
        ...
        </Dropdown>

Issue: This not very nice as you have to move the pointer to the dropdown text to get the tooltip.

2.- Tooltip containing all the Dropdown:

        <Tooltip
          content="Tooltip text"
          placement="bottom">
            <Dropdown
              size="sm"
              label="Dropdown button text">
              ...
            </Dropdown>
        </Tooltip>

Issue: This is not very nice when the tooltip is in the bottom as it is shown even when the mouse is over the dropdown menu items, hidding part of them (and not always is feasible to change the tooltip placement due to design restrictions).

Suggested feature:

I would suggest to include a new dropdown property to easily allow to use a tooltip only for the dropdown button.
If you have any other workaround it would be nice to know it otherwise.

Start by inspecting the existing Dropdown and Tooltip component APIs and their usage examples. Define how a new Dropdown property should apply the tooltip only to the button, including expected behavior while menu items are hovered; the issue does not name specific files or tests.
