Dump IInputProcessor when dump is called

We need to dump this process because it may become unresponsive.
Currently, it's missing from the dumps.

After this change, I'm finding the following data inside bugreport:
----- Waiting Channels: pid 1794 at 2022-07-01 21:08:01.751449995+0000 -----
Cmd line: /vendor/bin/hw/android.hardware.input.processor-service

sysTid=1794      binder_wait_for_work
sysTid=1804      futex_wait_queue_me

----- end 1794 -----
