src/include/cbfs.h: Added prototype for function to verify a stage after it has been loaded into DRAM

This support enables a user to implement a stage verification mechanism
AFTER the stage has been loaded into DRAM. This feature is currently
used by VBOOT_STAGE_VERIFICATION

TEST=Create a coreboot.rom image which has keyblock and VBLOCK
     with VBOOT version 2.1 structures. This is done by enabling
     CONFIG_VBOOT_STAGE_VERIFICATION. Verify that the image boots
     to authenticated payload.
