tests/uefi-test-tools: report the SMBIOS entry point structures
On UEFI systems, the SMBIOS entry point (a.k.a. anchor) structures are
found similarly to the ACPI RSD PTR table(s): by scanning the
ConfigurationTable array in the EFI system table for well-known GUIDs.
Locate the SMBIOS 2.1 (32-bit) and 3.0 (64-bit) anchors in the
BiosTablesTest UEFI application, and report the addresses in new fields
appended to the BIOS_TABLES_TEST structure.
