A bunch of maintenance fixes, the largest of which is getting the PTX simulation to work with CUDA 12. (#95)

* Fixing the formatter to always use a consistent format and running it on the codebase

* Update linux-so-version.txt

* Update Makefile

* A couple of unnecessary files that are lingering around

* Support CUDA 12

* Getting the PTX simulations to work with CUDA 12. The issue is that ptxas added more information (number of barriers and compile time). We have to parse these or lexx/yacc fail.

* Update ptxinfo.l

debug MACRO was ineffective

* Update gpgpusim_check.cmake

Update to make the CUDA version print a warning, not an error and updating the print to be more reflective of what the actual problem is.
