Performances improvement about parallel running of linters

Fixes #1785

• Performances improvements: when running linters in parallel, run in the same process only the linters from same descriptor and that can update the same sources (to avoid concurrency). Other linters can be run independently.

You could have the same capabilities but better runtime performances if you use a MegaLinter flavor:

• oxsecurity/megalinter/flavors/python@v5 (54 linters)
