Auto merge of #14498 - dpyro:image-orientation, r=canaltinova

Added image-orientation property

<!-- Please describe your changes on the following line: -->

Implemented as per the MDN documentation—I could not find a current CSS draft. I am not sure if this is the complete correct metadata for the longhand helper:
```
<%helpers:longhand name="image-orientation”
                   experimental=“True”
                   animatable=“False”>
```
Also I am not sure how to test this and would appreciate help in creating a testing strategy.
