network: add network_set_passphrase

Browse Source 
This lets other modules (like WSC) to set a plain text passphrase
as opposed to only allowing a PSK to be set. network_get_psk was
also updated to generate a PSK on-the-fly if required. Since WPA3
requires the raw passphrase to work, it makes sense to just store
the passphrase if we have it.
