ipn, ipn/ipnlocal: remove darwin & ios from goosGetsLegacyNetmapNotify

Browse Source 
The Apple clients' last consumer of the legacy Notify.NetMap field was
converted to peer deltas in tailscale/corp#44962, so tailscaled no
longer needs to build and emit full netmaps on the IPN bus for darwin
and ios. Windows is now the only remaining platform on the legacy path.

Updates #12542
