hugolib: Handle shortcode per output format

This commit allows shortcode per output format, a typical use case would be the special AMP media tags.

Note that this will only re-render the "overridden" shortcodes and only  in pages where these are used, so performance in the normal case should not suffer.

Closes #3220
