Make the reference implementation for InputClassifier HAL do nothing.
This is to allow cuttlefish to install this implementation.
It is safe for any device to install this implementation, and is
equivalent to not having the HAL running at all.
Test: boot up cuttlefish, and interact with the virtual device to ensure
that input works okay. Then 'ps -A | grep -i input' and ensure that the
HAL is running on the device.

The reset will be used to prevent an inconsistent stream of
events to be sent to the HAL.

The types added for input in InputClassifier HAL are not specific to
that HAL. These are common input definitions.
To allow for future reuse in this and other HALs, move these definitions
into a separate, type-only HAL android::hardware::input::common.
This will be similar to such existing HALs as:
hardware/interfaces/graphics/common
hardware/interfaces/camera/common
hardware/interfaces/audio/common

The new HAL will be responsible for processing touch video frames that
are received from InputClassifier stage.
After processing, the HAL will generate a classification of the current
gesture. This classification will later be provided to the app via
the MotionEvent.getClassification() public API.
The eventual goal is to classify each event stream as a force touch
or not a force touch.
An example implementation of the HAL is presented here. This code was
used for local testing on blueline, and should not be actually installed
or used in any way other than for reference.

Test: observed "detected deep press" logs when pressing with large
finger area on the touchscreen
