The main topic of this commit is that you can now index fragments (content heading identifiers) when calling `.Related`. You can do this by: * Configure one or more indices with type `fragments` * The name of those index configurations maps to an (optional) front matter slice with fragment references. This allows you to link page<->fragment and page<->page. * This also will index all the fragments (heading identifiers) of the pages. It's also possible to use type `fragments` indices in shortcode, e.g.: ``` {{ $related := site.RegularPages.Related .Page }} ``` But, and this is important, you need to include the shortcode using the `{{<` delimiter. Not doing so will create infinite loops and timeouts. This commit also: * Adds two new methods to Page: Fragments (can also be used to build ToC) and HeadingsFiltered (this is only used in Related Content with index type `fragments` and `enableFilter` set to true. * Consolidates all `.Related*` methods into one, which takes either a `Page` or an options map as its only argument. * Add `context.Context` to all of the content related Page API. Turns out it wasn't strictly needed for this particular feature, but it will soon become usefil, e.g. in #9339. Closes #10711 Updates #9339 Updates #10725
