[markdewing]

Summary

Add a debug message with the compute capability of the device
and the image when they're not compatible.

Add the debug message to the new plugin

openmp/libomptarget/plugins-nextgen/cuda/src/rtl.cpp

       // on any GPU with the same major revision and same or higher minor
       // revision.
