[cleanup] Remove a final static image from AnalysisResourceItemImpl

getImage() methods can directly call
SiriusEditPlugin.getPlugin().getBundledImage(image path), the plugin
contains an image cache and create the image only once. 

The static final Image field has been replaced by a static final String
to store only the image path.
