Implement profiler log writing at shutdown

Add a flag to enable writing profile data during shutdown
(--profiling-output-file=$FILE).

Add TaskProfilerDataSerializer.  This class is responsible for
collecting and outputing profiler data.  Currently, the collection part
is very simple, since ThreadData::ToValue() is static.  It should become
more substantial when we add support for multi-process profiler dumps.
This class has to be located outside of base/ because it needs to access
Chrome-specific functions (ie. for fetching the userAgent).

Move AutoTracking class to the chrome/browser/task_profiler directory.
It needs to access the TaskProfilerDataSerializer, but components in
base/ should not have access to this Chrome-specific class.
