Split InputFlinger into multiple libraries
This is the InputFlinger FE/BE split as detailed in
go/arc++inputflinger-split.
We split libinputflinger into the following dynamic libraries:
- libinputflinger: Acts as the frontend for inputflinger and implements
InputDispatcher and InputManager.
- libinputreader: Acts as the backend for inputflinger and impliements
InputReader and EventHub, and adds a InputReaderFactory to create
the InputReader.
- libinputflinger_base: Contains the common logic that is shared
throughout InputFlinger, and contains the definitions for
InputReaderInterface (in InputReaderBase.h) and
InputListenerInterface (in InputListener.h).
Bug: 119264687
Test: manual: Build, run, and test input (touch, mouse)
