Adds constants and runner for animations

Adds constants and runner for animations

Its not yet wired up to anything, but the basics and plumbing are
there. I'm hoping this is rich enough for animations we want to
support.

You may want to have these in a different file; if the mojom file is called
view_manager_constants, I wouldn't expect struct declarations.

If ServerView's have arbitrary transforms now, do these need to be pumped to the
View? (How do arbitrary transform animations effect input event processing?)

The client lib will definitely want transform too. I have to think about whether
it makes sense to send animation values back to the client.

We have to resolve what the right way is to handle input events. The surface
service knows where all the surfaces are and can do hit testing. That isn't how
we're doing things now though.
