Add InputDispatcherRule to print the key events dispatched from system_server. 

See
https://source.corp.google.com/h/android/platform/superproject/main/+/main:cts/libs/input/src/com/android/cts/input/DebugInputRule.kt

Locally we can execute `adb shell setprop log.tag.InputTransportPublisher DEBUG` to enable the InputDispatcher logs.

I want to debug why "Ctrl+W" DOWN events in not received by TAPL and to which window is the events delivered.

Test: Manual
Flag: NA
