payloads/Kconfig: Add flat binary as payload option

This add another choice option for adding a flat binary instead of an
ELF or some other payload. It keeps the IS_PAYLOAD_FLAT_BINARY hidden in
the menuconfig because it is generally not configurable but dependent on
the payload you selected.
CONFIG_PAYLOAD_OPTIONS has been exposed to be configurable in commit
f0055e4a81 (payloads/Kconfig: Add flat binary as payload option) as part
trying to enable flat binary payloads. CONFIG_PAYLOAD_OPTIONS do not
need to be configurable though unless you have a flat binary. The patch
therefore takes a different appraoch by adding a new payload type
besides PAYLOAD_ELF and PAYLOAD_FIT.
