vboot: copy data structures to CBMEM for downstream use

Browse Source 
For platforms that do not employ VBOOT_STARTS_IN_ROMSTAGE,
vboot verification occurs before CBMEM is brought online.
In order to make vboot data structures available downstream,
copy vb2_working_data from CAR/SRAM into CBMEM when CBMEM
comes online.  Create VBOOT_MIGRATE_WORKING_DATA config
option to toggle this functionality.
