Description

Currently there is no support for dismissing modal routes with the keyboard (usually with the 'escape' shortcut key). This PR adds a new general DismissIntent and corresponding DismissAction. The intent is mapped to the escape key in the default shortcut map, and modal routes (dialogs, popups, drawers, etc) will now look for this and dismiss themselves when it is triggered.

Tests

I added a simple test to verify that a modal dialog can be dismissed with the 'escape' key.

This looks pretty good. We'll need to make sure that it is the right thing for the web, but otherwise I think all platforms use escape in this way.

Yeah, from a cursory look of a few webapps, it appears that escape to dismiss popups is pretty common.

I'll go ahead and flush this out with docs and tests to get this ready for review. Any thoughts about putting this on the _ModalScope? It seemed like the best place to me, but I am not that familiar with the route code.

Renamed the DismissIntent and Action to CancelIntent and CancelAction…
