Remove white space at end of lines in our code

We should remove white space at the end of the lines in our code, and also have a precommit and/or github action that checks our code for this. This would be something that we should do throughout the code, but also have some tools that check this for us.

Note, that in @negin513 PR #1768 she added a pre-commit hook that does this for the python code. That work should come in, as well as extending it for our FORTRAN, perl, and XML code.

Definition of Done:
- [ ] Bring in #1768
- [ ] Extend that to also run on the FORTRAN, perl and XML code
- [ ] Add a github action that checks it in PR's?
