This adds setup code and utility functions for ATK to the Python environment. I also needed to prevent front-end accessibility checks (AccessibilityUtils) from force disabling accessibility for a11y engine tests. Although the tests re-enabled it anyway, this seems to break AT-SPI's interaction with our ApplicationAccessible. Disabling it really doesn't make sense in this case anyway. This patch includes a simple role test to show all of this working. Differential Revision: https://phabricator.services.mozilla.com/D192911
