Add noop implementation of the IVmCapabilitiesService

This implementation will be used in cuttlefish for mixed device testing.

Unfortunately, cuttlefish can't use the default implementation, since
it neither doesn't support pVMs not runs pkvm as hypervisor.

Additionally, this patch adds a simple VTS test to ensure that HAL was
setup correctly.
