This allows for constructs like:
```
{{ $filters := slice (images.GaussianBlur 8) (images.Grayscale) (images.Process "jpg q30 resize 200x") }}
{{ $img = $img | images.Filter $filters }}
```
Note that the `action` option in `images.Process` is optional (`resize` in the example above), so you can use the above to just set the target format, e.g.:
```
{{ $filters := slice (images.GaussianBlur 8) (images.Grayscale) (images.Process "jpg") }}
{{ $img = $img | images.Filter $filters }}
```
Fixes#8439
Which supports all the existing actions: resize, crop, fit, fill.
But it also allows plain format conversions:
```
{{ $img = $img.Process "webp" }}
```
Which will be a simple re-encoding of the source image.
Fixes#11483
Change the default cache directory to `$TMPDIR/hugo_cache_$USER`, so
that multi-user systems do not have caches that interfere with each
other. The other cache-choosing logic (e.g. Netlify exceptions,
configuration options) are not affected.
Fixes#7391
strings.HasPrefix already has an alias of hasPrefix
but strings.HasSuffix has no such alias.
This PR adds a hasSuffix alias to the tpl function with corresponding
function documentation.
It also adds a Minor update to the hasPrefix function documentation
re: keywords and relatedfuncs.

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.

So you can do `process.env.HUGO_PUBLISHDIR` in your `postcss.config.js` to figure out where Hugo publishes
its files.
Note that the value will always be an absolute file path and will point to a directory on disk even when running `hugo server` in memory mode.
If you write to this folder from PostCSS when running the server, you could run the server with one of these flags:
```
hugo server --renderToDisk
hugo server --renderStaticToDisk
```
Fixes#10554
