Cocoa: Ignore monitors which are mirroring another

Browse Source 
Currently monitors which are mirroring another one are returned by
`glfwGetMonitors` but their `ns.screen` is `NULL`. Some functions like
`glfwGetMonitorContentScale` and `glfwGetMonitorWorkarea` assert that
`ns.screen` is not `NULL`. Since mirrored monitors are logically the
same we should only consider the primary monitor and ignore the
non-primary ones.
