Compile SU2 with Mutation++ for regression tests

[WallyMaier]

Proposed Changes

This updates the version of MPP for use in the NEMO solver.

Is there a way to include a MPP test case for the regressions?

I think this is correct. I updated the SHA and checked the mutation++ submodule to version said SHA-Tag.

Try changing regression.yml to compile with Mutation and we'll see if we need to update the docker images.

True. I know there was (maybe still is) an issue with CoDi and MPP...not completely sure.

@pcarruscag It looks likes Mutation++ has some warnings/errors. I am not sure how to only turn off the return-type warning->error workflow.

Now you need to set the environment variables to pickup mutation in this script https://github.com/su2code/Docker-Builds/blob/master/test/runTests.sh via PR to the Docker-Builds repo.

I'll change the scope of this for now to just allowing tests to run with mutation++
The NEMO group can add tests and decide whether to update the version later.
