SMBIOS: Update Type 0 struct generator for machines >= 2.1
Update how type 0 (bios info) structures are generated, as follows:
- convert bios_characteristics field to uin64_t (instead of
uint8_t[8]), as described in the current smbios spec (v2.8)
- enable "virtual machine" bit in bios_characteristics_extension_bits
- add command line option to enable "uefi supported" bit in
bios_characteristics_extension_bits
These updates should make this optional structure more useful when
used with edk2/ovmf. Only pc machines >= 2.1 are affected, and only
when a type 0 structure is explicitly specified on the command line.
