bios-tables-test: Add complex SRAT / HMAT test for GI GP

Add a test with 6 nodes to exercise most interesting corner cases of SRAT
and HMAT generation including the new Generic Initiator and Generic Port
Affinity structures.  More details of the set up in the following patch
adding the table data.
