I think that depends on the kernel driver for the wifi interface, and on
the hardware's capability.  But if you have two wifi interfaces, then as
long as one driver supports P2P GO and one driver supports client, then:

Yes.  Or two different interfaces but using the same
wpa_supplicant/wpa_cli process.  No reason to use two different
wpa_supplicant processes, since the same process can easily control any
number of wifi interfaces at the same time, independently.
