This adds a new "nop" driver that does nothing. This can be selected at runtime either with the COGL_DRIVER=nop environment variable or by passing COGL_DRIVER_NOP to cogl_renderer_set_driver() Adding the nop driver gives us a way to test workloads without any driver and hardware overheads which can help us understand how Cogl's state tracking performs in isolation. Having a nop driver can also serve as an shell/outline for creating other drivers later.
