all: pass 'hints' from secret agent to ws_wpa_eap_new

The secret agent requests contain two parameters that aren't currently
used when handling Wifi network connections: the setting name and hints.
Those parameters turned out useful with 802.1X / EAP authentication with
NM's IWD backend where it passes a specific 802_1x setting key name that
is being requested in the 'hints' array, one of: identity, password or
private_key_password.
nmcli already gained support for handling such agent requests in
1a6e53808db8bb8e75317fd5feacd74a9a98860f (which was obviously much
easier) so this is an attempt to let the src/wireless-security/* classes
in nm-applet also handle these requests as intended.

A new libnma function nma_wifi_dialog_new_for_secrets is added to
receive the values from setting name and hints without changing existing
API.
