ncm: add weak callback for initial link state

Browse Source 
netd_init resets link_is_up to a compile-time default, which is
incorrect when the host reboots without power-cycling the device.
Add tud_network_default_link_state_cb() so applications can return
the actual physical link state. The weak default preserves existing
CFG_TUD_NCM_DEFAULT_LINK_UP behaviour.
