ACPI: Add vmgenid blob storage to the build tables

Browse source 
This allows them to be centrally initialized and destroyed

The "AcpiBuildTables.vmgenid" array will be used to construct the
"etc/vmgenid_guid" fw_cfg blob.

Its contents will be linked into fw_cfg after being built on the
pc_machine_done() -> acpi_setup() -> acpi_build() call path, and dropped
without use on the subsequent, guest triggered, acpi_build_update() ->
acpi_build() call path.
