Add in-process Fortran benchmark utility and implement all benchmarks

[PEZ]

I have:

• Read the project README, including the benchmark descriptions
• Read the PR template instructions before I deleted them
• Understood that if I have changed something that could impact performance of one or more contributions, I should provide results benchmark runs, using the run.sh script, from before and after the change.

Description of changes

This adds Fortran to the list of languages ported to the new in-process runner.

• Fixes: Fortran in-process runner #372

Benchmark results:

• https://pez.github.io/languages-visualizations/#https://gist.github.com/PEZ/411e2da1af3bbe21c4ad1d626451ec1d

(Select the M4 Max run from the dropdown.)
