tests: acpi: add acpi_find_rsdp_address_uefi() helper
introduce UEFI specific counterpart to acpi_find_rsdp_address()
that will help to find RSDP address when [OA]VMF is used as
firmware. It requires guest firmware or other guest app to place
1Mb aligned UefiTestSupport structure (defined in this patch)
in RAM with UefiTestSupport::signature_guid set to
AB87A6B1-2034-BDA0-71BD-375007757785
For test app details see commit
(09a274d82f tests: introduce "uefi-test-tools" with the BiosTablesTest UEFI app)
