Bootstrap IInputFlingerRust - the Rust component of inputflinger
When inputflinger boots, we create the Rust component of inputflinger,
which we interact with from C++ through the local AIDL interface
IInputFlingerRust.
After we have access to the IInputFlingerRust binder object in C++, all
communication between C++ and Rust can take place purely through AIDL
interfaces.
To initialize the interface, we must first pass a raw pointer to an AIDL
implementation across the language barrier through some other means. In
this CL, we use cxxbridge to bootstrap the local AIDL interface for
IInputFlingerRust.
