Do all (embedded) EFI systems have a frame buffer?
That's a good question. I don't know if all EFI firmwares are expected to provide a GOP or not. But even the u-boot EFI stub provides one, if video output is supported by u-boot on that system.
No, GOP is only mandatory for systems with a graphical console device even assuming things fully conform to the spec. Indeed I've got a non-embedded EFI based system sitting next to my desk here which only has a serial console, never mind anything embedded.
