Add tracing for InputConsumer lifetime
This will help understand when it's created and destroyed. This also helps disambiguate between multiple InputConsumers in the same process.
Test procedure:
1. Add "system tracing" to quick settings from developer options (enable
the quick settings tile for system tracing)
2. Start system tracing via UI of quick settings
3. Open all apps and do some swipes
4. Click "stop tracing"
5. Pull the logs to the device `adb pull /data/local/traces/ ~/trace`
6. Go to https://ui.perfetto.dev/
7. Click "open trace file" and navigate to the local file
8. In the trace, open the process of interest. In this case, it's the
launcher process
9. Scroll down to "InputConsumer processing"
10. The "cookie" field of each entry is the sequence number of this
event (but not the event id).
Bug: 311142655
Test: perfetto test procedure described above
