The NNAPI originally planned to have updated platform drivers delivered
through GMSCore. These updatable drivers would be retrieved through the
NN sAIDL utility code, and were known to be updatable through
Manager.cpp's Device::isUpdatable query.
However, the NNAPI ultimately did not move forward with its updatability
plans. This CL removes the updatability check in the NN AIDL utility
code.

The NNAPI is a Mainline Module, and its runtime version is determined by
an Android Feature Flag to remotely rollout and rollback Feature Levels
as needed. This change propagates the maximum feature level version
allowed by the runtime to the HAL utility code, and clamps the utility
code's version to the version allowed by the runtime.

Test: logged driver version, set current_feature_level, and verified the
driver version was clamped by current_feature_level

This CL alters the AIDL utility "getDevices" to return whether or not a
service is updatable. This CL additional removes IDevice::isUpdatable
because it is now redundant with the changes to "getDevices".

This CL implements the canonical IDevice, IPreparedModel, and IBuffer
interfaces for the 1.0, 1.1, 1.2, and 1.3 NN HIDL HAL interfaces.
Further, it introduces "Resilient" adapter interfaces to automatically
retrieve a handle to a recovered interface object after it has died and
rebooted.
This CL also updates the conversion code from returning nn::Result to
nn::GeneralResult, which includes a ErrorStatus code in the case of an
error.
Finally, this CL introduces a new static library
neuralnetworks_utils_hal_service which consists of a single function
::android::nn::hal::getDevices which can be used by the NNAPI runtime to
retrieve the HIDL services without knowing the underlying HIDL types.
