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.

// This file is a snapshot of an AIDL file. Do not edit it manually. There are

// two cases:

// 1). this is a frozen version file - do not edit this in any case.

// 2). this is a 'current' file. If you make a backwards compatible change to

//     the interface (from the latest frozen version), the build system will

//     prompt you to update this file with `m <name>-update-api`.

//

// You must not make a backward incompatible change to any AIDL file built

// with the aidl_interface module type with versions property set. The module

// type is used to build AIDL files in a way that they can be used across

// independently updatable components of the system. If a device is shipped

// with such a backward incompatible change, it has a high risk of breaking

// later when a module using the interface is updated, e.g., Mainline modules.
