Per Kernel Output Files

[MrBurmark]

This writes a file for each kernel by combining the relevant parts of our normal output files. These files are written into a RAJAPerf-kernels directory to avoid cluttering the main directory.
This writes a single file with all the data for all of the kernel variant tunings.

Most of the changes involve changing the output code to only print the variant tunings defined for the given kernel to avoid excessive "Not Run" outputs.

Summary

• This PR is a refactoring, feature
• It does the following:
  • Modifies/refactors the output code to avoid extraneous outputs in some cases
  • Adds per kernel output files at the request of me
  • Adds kernel-data output file

Here is an example RAJAPerf-kernel-run-data.csv file if you ran Hip variants of the Stream kernels.

Kernels run on 4 MPI ranks

Super nice! I'm super interested in trying out this feature, if I can get a day or two I can give some user experience feedback.
