Add binder transaction tracking.

Add the ability to am to be able to track binder transact calls. This
will help us diagnose excessive IPC calls.

This CL adds the trace-ip command to am. The usage is,

To start binder transaction tracking,
am trace-ipc start
To stop tracking and dump the data to a file,
am trace-ipc stop --dump-file <FILE>
