Define cc::TransformOperations and webkit::WebTransformOperationsImpl

This ports the implementation of WebTransformOperations into cc::TransformOperations, Also, behind #if WEB_TRANSFORM_OPERATIONS_IS_VIRTUAL, this makes cc use TransformOperations instead of WebTransformOperations; defines a new class WebTransformOperationsImpl that implements WebTransformOperations using an instance of cc::TransformOperations; defines WebCompositorSupportImpl::createTransformOperations; and makes compositor_bindings use WebTransformOperationsImpl instead of WebTransformOperations (extracting the underlying cc::TransformOperations before calling into cc). 

This is step 1 of the 3-step plan outlined at https://chromiumcodereview.appspot.com/11745018 for moving the implementation of WebTransformOperations into chromium.
