Handle Esc key for multiple components

[jgiardino]

There are several components that should be dismissible via the Esc key:

• Modal
• Popover
• Dropdown when expanded
• Tooltip

Some of these components can be nested, e.g. a modal with a dropdown or tooltip. For these cases, the Esc key should not dismiss everything that's open. Instead, the Esc key should only dismiss the last component that was expanded/opened.

As part of this issue, we need provide one of the following:

• ability to manage the Esc key behavior for multiple components
• a POC that demonstrates this ability, documentation on how it was achieved, and a new issue to capture how we want to share this information with consumers

@jgiardino I was taking a look at these components, and I think they all currently support Esc key interaction. I think you make a valuable point about nested components, do you think that part of the issue is related to this issue?

The listed components have been retested - and a dropdown in a modal example was added to the modal docs. It seems that the behaviors are working as expected.
