Code coverage improvements (#1665)

* Increased max stack size to 640

* Added new binary for executing unit tests

Added new unit tests for argcheck.cc and alt_rsmi.cc files

Modified the method to execute unit tests to cover static methods
by using a bash script to convert static to non-static functions
and variables on the fly restricted to debug build type.
