payloads: Load coreinfo as a secondary payload

This allows coreinfo to be added to CBFS as a 'secondary'
payload on x86 systems, to be loaded by the main payload
if desired.

Selecting this option, which defaults to no, builds the coreinfo
payload and adds it to CBFS as `img/coreinfo` which can then be
loaded by for example SeaBIOS or GRUB.
