Convert InputClassifier HAL to AIDL

No changes to the HAL are made in this change, we are only updating the
interface to use AIDL.
At the same time, the HAL is getting renamed to 'InputProcessor', which
will mean that it's more general-purpose than just classification. We
will be adding more stuff to this HAL in the future.

Test: integration tested with other framework changes on top
