Vulkan: Enforce ContextPriority in ShareGroup and with EGLImage This CL enforces single Context Priority for all Contexts in a Share Group. This is necessary until Vulkan Semaphores will be used to automatically synchronize Resource access between Contexts. Contexts Priority updated when new Contexts is added to the Share Group. New Priority will be the highest among all ever existed Contexts (except if Priority is locked). When Contexts Priority changes, all flushed commands are submitted to the old VkQueue and semaphore is inserted into the new VkQueue. Currently opened RenderPasses and commands will not be flushed. When EGLImage is used in a Context, all Contexts in that Share Group locked (forever) to the Default Priority (Medium). This is done to simplify the implementation and because of the current limitations (lack of mutex protection across Context Share Groups). Notes: - the EGL_CONTEXT_PRIORITY_LEVEL_IMG will report initial priority. - below tests fail on G996B without this CL.
