class PciDriverTests_TestRunner_Class

This test builds the foundation for PCI Protocol tests. After the

IsolatedDevmgr loads a new platform bus, it will bind the fake PCI bus

driver. The fake bus driver creates a real device backed by the fake ecam,

which results in our protocol test driver being loaded. The protocol test

driver exposes a FIDL RunTests interface for the test runner to request tests

be run and receive a summary report. Protocol tests are run in the proxied

devhost against the real PCI protocol implementation speaking to a real PCI

device interface, backed by the fake bus driver.
