Merged debug.sh into run.sh.

@mantaraya36:

If this OK, the next step is to adapt the changes to the AlloProject *run.sh*.

It might be overkill, but the two possible *cmake* commands could be reduced to one if *CMakeLists.txt* switches on if `ALLOSYSTEM_DEBUGGER` is defined and also sets `CMAKE_BUILD_TYPE` based on that.
