This CL introduces unit tests to validate the V1_X::utils::Device, *PreparedModel, and *Buffer adapter classes. It does so by mocking the underlying HIDL interface in order to simulate a driver returning bad data, HIDL transport failures, and service crashes. Note that the purpose of these new tests is to validate the adapter classes themselves, not the HIDL interfaces they use. For example, because nn::IPreparedModel does not currently define a method for configuring a burst execution, V1_[23]::utils::PreparedModel similarly does not use hardware::neuralnetworks::V1_[23]::IPreparedModel's configureExecutionBurst method. This CL also introduces unit tests to validate the utils::Resilient* adapter classes, and mocks DEAD_OBJECT failures to ensure that the underyling object can be recovered appropriately.
