Implement ci/cd view rendering for doxygen documentation

[Alex2772]

In AUI docs, some view pages have image preview of the view (i.e. https://aui-framework.github.io/develop/classAButton.html for button). However we have to make these images manually.

I think it would be great to automate creating images of views with ci/cd.

1. On ci/cd pipeline, make an aui application which renders particular view with software renderer to an png image.
2. Put these pngs to the documentation pipeline.
