hw/arm/virt: build SMBIOS 19 table
Use the base_memmap to build the SMBIOS 19 table which provides the address
mapping for a Physical Memory Array (from spec [1] chapter 7.20).
This was present on i386 from commit c97294ec1b9e36887e119589d456557d72ab37b5
("SMBIOS: Build aggregate smbios tables and entry point").
[1] https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.5.0.pdf
The absence of this table is a breach of the specs and is
detected by the FirmwareTestSuite (FWTS), but it doesn't
cause any known problems for guest OSes.
