Vsock test depends on two process groups running simultanously:
VirtManager+CrosVM and vsock_server. This was orchestrated by a Java
test runner running on the PC. With all the recent changes to the test,
it is now possible to run the former from AndroidTest.xml (and
eventually that will be completely removed) and convert vsock_server to
a GTest binary installed and invoked directly by TradeFed.
A common GTest class VirtualizationTest is added for hosting individual
test cases and sharing common code. Vsock test is converted to a single
TEST_F instance.
The test target is now called VirtualizationTestCases (dropped Host).
