AGESA: Add common callouts

Most of the callouts are not specific to board or even family.
Start new file with default callouts doing nothing and returning
either AGESA_SUCCESS or AGESA_UNSUPPORTED.

Also add callout for returning empty IdsIdData. This feature is
not used and could be easily overriden at board-level at later time.
