Fixes issues the app developers have raised with the WindowInsetsAnimation API: - it really makes more sense to have the Animation as the outer class, and the Callback nested within - it was not obvious previously that multiple animations could be running at the same time. A new argument to onProgress now makes this abundantly clear by passing in the list of running animations. - The dispatch mode really fits better as a final property on the callback, rather than it being queried once from a getter. Also fixes lint warnings. Fixes: 143556682 Test: make checkapi; atest WindowInsetsControllerTests Change-Id: I8cd8faac70dd5a15d779d2c983f0a0ea5d6bbd8e
