sculpt: add trace_logger as optional launcher

This patch adds the trace-logger utility to the default set of packages
along with an optional launcher. With this change, only two steps are
needed to use Genode's tracing mechanism with Sculpt:

- Add 'trace_logger' to the 'launcher:' list of the .sculpt file

- Either manually select the 'trace_logger' from the '+' menu,
  or add the following entry to the deploy configuration:

    <start name="trace_logger"/>

By default, the trace logger is configured to trace all threads
executed in the runtime subsystem and to print a report every 10
seconds. This default policy can be refined in the launcher's <config>
node. Note that the trace logger does not respond to configuration
changes during runtime. Changes come into effect not before restarting
the component.

Issue #4448
