Convert InputVerifier to rust

To establish some basic rust infrastructure for input code, convert the
InputVerifier into rust.

Currently, we use bindgen for interfacing between cpp and rust. In a
future CL, this may be changed to an aidl interface instead.

The logs and verifications can be enabled via:
adb shell setprop log.tag.InputTransportVerifyEvents DEBUG
adb shell setprop log.tag.InputVerifierLogEvents DEBUG
adb shell setprop log.tag.InputDispatcherVerifyEvents DEBUG
