Image: Add srcset attribute

[drilko]

Describe the feature you would like to see added

On the documentation site it says:" Image is used as the native img element and supports all properties that the native element has.", but it is missing srcset attribute.
It would be beneficial to support it as well.

Is your feature request related to a problem?

Nope

Describe the solution you'd like

Add srcset and perhaps previewImageSrcset inputs to the component.

Describe alternatives you have considered

I could probably "hack it" in some way by using *ngIf or media queries but it would be better to support srcset attribute as you already use native img element.

Additional context

Just a quick note, if we support srcset attribute we should also support sizes

Note: If the srcset attribute uses width descriptors, the sizes attribute must also be present, or the srcset itself will be ignored.

[tomer953]

The implementation however should not be too complex:

@Input() srcset: string | undefined;
@Input() sizes: string | undefined;

<img [attr.src]="src" [attr.srcset]="srcset" [attr.sizes]="sizes" … />
