This also makes the required changed to src, tests, and tools. The few public APIs modified by this change appear to be unused outside of Skia. Removing these from the public API makes it easier to ensure users are no longer using them. This also updates GrGpu::wrapBackendXXX and the ::onWrapBackendXXX methods to clarify ownership.
