[metal] Add commands scheduled sync object We need a thread-safe way to wait for ANGLE Metal command buffers to be scheduled for IOSurface synchronization with DrDC + Graphite on Mac. The existing eglWaitUntilWorkScheduledANGLE API isn't thread-safe as it reaches into ContextMtl innards to flush the command buffer. This CL adds the EGL_ANGLE_metal_commands_scheduled_sync extension which introduces a EGL_SYNC_METAL_COMMANDS_SCHEDULED_ANGLE sync object type. This sync object is signaled when pending Metal commands are scheduled to run on the GPU (MTLCommandBufferStatusScheduled). These sync objects are thread-safe - eglClientWaitSync() can be called on any thread even without a current context which is needed for DrDC + Graphite on Mac.
