Add .editorconfig file for basic formatting

EditorConfig is a specification to define the most basic code formatting
stuff, and it's supported by many editors and IDEs, either directly or
via plugins, including VSCode/VSCodium, Vim, emacs and more.

It allows to define formatting style related to indentation, charset,
end of lines and trailing whitespaces. It also allows to apply different
formats for different files based on wildcards, so for example it is
possible to apply different configs to *.{c,h}, *.py and *.rs.

For the security-tracker, modelled after the very same change in the
linux project, defining a .editorconfig might help to those people that
work on different projects with different indentation styles, so they
cannot define a global style. Now they will directly see the correct
indentation on every fresh clone of the project.
