qtest/bios-tables-test: Add tests for legacy smmuv3 and smmuv3 device
For the legacy SMMUv3 test, the setup includes three PCIe Root Complexes,
one of which has bypass_iommu enabled. The generated IORT table contains
a single SMMUv3 node, a Root Complex(RC) node and 1 ITS node.
RC node features 4 ID mappings, of which 2 points to SMMU node and the
remaining ones points to ITS.

       pcie.0 -> {SMMU0} -> {ITS}
{RC}   pcie.1 -> {SMMU0} -> {ITS}
       pcie.2            -> {ITS}
       [all other ids]   -> {ITS}

For the -device arm-smmuv3,... test, the configuration also includes three
Root Complexes, with two connected to separate SMMUv3 devices.
The resulting IORT table contains 1 RC node, 2 SMMU nodes and 1 ITS node.
RC node features 4 ID mappings. 2 of them target the 2 SMMU nodes while
the others targets the ITS.

        pcie.0 -> {SMMU0} -> {ITS}
{RC}    pcie.1 -> {SMMU1} -> {ITS}
        pcie.2            -> {ITS}
        [all other ids]   -> {ITS}
