hv: quirks: SMBIOS passthrough for prelaunched-VM

Browse Source 
This feature is guarded under config CONFIG_SECURITY_VM_FIXUP, which
by default should be disabled.

This patch passthrough native SMBIOS information to prelaunched VM.
SMBIOS table contains a small entry point structure and a table, of which
the entry point structure will be put in 0xf0000-0xfffff region in guest
address space, and the table will be put in the ACPI_NVS region in guest
address space.

v2 -> v3:
uuid_is_equal moved to util.h as inline API
result -> pVendortable, in function efi_search_guid
recalc_checksum -> generate_checksum
efi_search_smbios -> efi_search_smbios_eps
scan_smbios_eps -> mem_search_smbios_eps
EFI GUID definition kept
