tools (common/template): add filter to get media types:
Add 2 filters to get main type and subtype of media type. Jinja2 and Nunjucks don't handle
slices in the same way (Python way for Jinja2, JS way for Nunjucks), making it difficult
to retrieve main type of a media from media type. Thoses filters work in both cases.
