The goal of this commit is to remove all dependency to legacy in the
wysiwyg because the wysiwyg has to be loaded on a lot of form view
(through the html_field).
To remove the dependencies, all the legacy widget that the wysiwyg
uses had to be converted to owl. In order to finish the PR faster,
only a partial conversion of the widgets is done, changing only the
part of the code that was necessary for it to work instead of
rewriting the whole widget from scratch. Another pass should be done
to convert all those widgets to fully embrace the owl paradigm.
