vircpi: Add PCIe 5.0 and 6.0 link speeds

The PCIe 5.0 and PCIe 6.0 standards define new link speeds:
32GT/s and 64GT/s, respectively. Update our internal enum to
include these new speeds. Otherwise we format incorrect XML:

  <pci-express>
    <link validity='cap' port='0' speed='(null)' width='16'/>
    <link validity='sta' speed='16' width='16'/>
  </pci-express>

Like all "good" specifications, these are also locked behind a
login portal. But we can look at pciutils' source code: [1] and
[2].
