Add egl::ShareGroup class to abstract the share context group Vulkan backend has a barrier tracker that tracks memory barrier needs of all shared resources. Because the buffer/texture objects are shared resources within a shared group, the tracker can not live in a context. Putting it in a device/renderer requires locks. It fits perfectly in a shareGroup object. The work is already done at API level to handle the mutex lock for shared context access so that no extra lock needs to be taken in the backend. This CL adds egl::ShareGroup class that represents the object that are shared among all share context group. At the front end this usually will include all the shared resource managers (not done in this CL). The ShareGroup object is accessible from gl::State object. This CL also adds ability for backend driver to allocate implementation specific ShareGroupImpl object. Vulkan backend will then use it to keeps the barrier tracker and other things that naturally fits the share group concept.
