smbios: Add option VPD_SMBIOS_VERSION that reads BIOS version from a VPD variable

Browse Source 
If VPD_SMBIOS_VERSION is selected, it would read VPD_RO variable that can
override SMBIOS type 0 version.

One special scenario of using this feature is to assign a BIOS version to
a coreboot image without the need to rebuild from source.
VPD_SMBIOS_VERSION default is n.

Tested=On OCP Delta Lake, dmidecode -t 0 can see the version being updated
from VPD.
