This commit adds a `rawSrcset` attribute as a replacement for the
`srcset` attribute. The `srcset` attribute cannot be set statically
on the image directive because it would cause images to start
downloading before the "loading" attribute could be set to "lazy".
Changing the name to `rawSrcset` allows the directive to control
the timing of image loading. It also makes it possible to support
custom loaders for `srcset` file names. Rather than having to repeat
the image origin for each image, the existing `rawSrc` value and
image loader can be composed to generate each full URL string. The
developer must only provide the necessary widths for the `srcset`.
For example, the developer might write:
```markup
<img rawSrc="hermes.jpg" rawSrcset="100w, 200w" ... />
```
with a loader like:
```js
const loader = (config) => `path/${config.src}?w=${config.width}`;
```
and the img tag will ultimately be set up as something like:
```markup
<img src="path/hermes.jpg?w=100" srcset="path/hermes.jpg?w=100 100w, path/hermes.jpg?w=200 200w" .../>
```
