task profiler: project configuration files clean up

The sample applications for task profiling requires a default
project configuration file that can be used as reference for
any other board.

Quark SE dev board has some optional optimizations that can
be added using the prj_quark_se_devboard.conf file.

Some redundant symbols were removed to simplify the reading
of the configuration.
