SLVS-1668 Include header file language in the VCX command (#5861)

[SLVS-1668](https://sonarsource.atlassian.net/browse/SLVS-1668) Part of SLVS-1637 See the linked ticket for details about the problems we identified. This PR introduces the following changes: - To communicate the header file language, I am adding the relevant switches to the generated command in the header case as well. This helps analyze C headers as such when they are located inside C VCX projects. - Since `HeaderFileLanguage` is no longer needed, I am removing it from `FileConfig`.
