CC Animation: Move files from cc_blink to Source/platform/animation

Disclaimer: This CL is only about moving files and sections of code.

We:

- Remove Web prefixes on files/classes and add Compositor prefix where necessary.

- Move exported/WebTransformKeyframe.cpp and exported/WebFilterKeyframe.cpp
to animation/ to group them with their headers.

- Move CompositorFilterOperations not to animation/ but to graphics/ folder,
because it's a property of WebLayer.

- Introduce CompositorFactory singleton (works as Platform) to create CC objects
in blink.
All animation methods are moved from CompositorSupport to CompositorFactory.
Other methods are also expected to be moved there.

- Decouple WebLayer and WebCompositorAnimation interfaces
by using cc::Animation class.
It allows us to make WebCompositorAnimation non-public.
WebLayer animation dependencies will go away when we erase the old animation system
(it's already disabled). http://crbug.com/575041

- Move static asserts from content/child/assert_matching_enums.cc to
Source/platform/WebCompositorAnimation.cpp (so the enum becomes non-public).

What's next (separate CLs):
- Remove virtual functions (when gmock-based tests erased)
- Remove redundant enum declarations (using alias).
- Erase the animation delegate adapter.
