Trigger a flush() when the command graph contains too many objects If an App repeatedly issues GL commands like glTextImage2D without a finish/flush/draw, it's possible for ANGLE to exhaust the available Vulkan memory allocations and exceed VkPhysicalDeviceLimits::maxMemoryAllocationCount. When this occurs, the Vulkan validation layers will trigger an error and cause dEQP tests to fail. This change will query the backend if a flush() should be performed during each of the GL delete calls, and perform it if necessary. This will cause a queue submission and a Serial increment, allowing the allocated memory to be freed, preventing the validation errors.
