This CL scopes the ARIA Notify API to accept only a string `announcement` and a ax::mojom::AriaNotificationPriority `priority` (values of which can be "high" or "normal", with "normal" being the default value). This API shape will serve as V1 of the feature, as agreed upon by the ARIA working group: https://github.com/w3c/aria/issues/2426 Future versions of the API may include properties of `interrupt` and `notification_id` (soon to be renamed `type`). More information about these properties, and the feature in general, can be found in the explainer: https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/Accessibility/AriaNotify/explainer.md This CL gates the use of `interrupt` and `notification_id` behind the "AriaNotifyV2" feature flag. As part of the process of serializing the ARIA notification attributes, `notification_id` will be passed to the AXNodeData as an empty string and `interrupt` will be passed as kNone unless the AriaNotifyV2 flag is enabled. We cannot even read the value of the `notification_id` or `interrupt` properties that may be passed by the web author as a part of V1 -- if we don't avoid reading the properties, then feature detection for those properties will be enabled. See more: https://github.com/w3c/aria/issues/2426#issuecomment-2634700360 This CL also adds new tests that use the AriaNotifyV2 feature flag. AX-Relnotes: This feature is behind a feature flag so it should not impact the experience of users who are not enabling the flag.
