The OSX 10.12 SDK added CAAnimationDelegate and CALayerDelegate protocols and
used them to strongly type some delegates that we use. This patch fixes the
compilation errors that arise on the the SDK. Can you please take a look?

I expect this CL to run into the same issues as
https://codereview.chromium.org/2253863002/ -- I'd be happy to move the empty
definitions for CAAnimationDelegate and CALayerDelegate to a proper place, once
I know what that is.

Can you please take a look at this CL?

I previously assigned this to nektarios based on a comment, without actually
looking through OWNERS. Sorry!
