[Compact Profile 2] - Smarthome UI bundle depends on Full JRE packages

[svilenvul]

Looking at the report generated by openhab/static-code-analysis#283, I see that several packages in org.eclipse.smarthome.ui bundle depend on packages in the Full JRE :

• org.eclipse.smarthome.ui.chart depends on java.awt.image
• org.eclipse.smarthome.ui.internal.chart depends on java.awt.image
• org.eclipse.smarthome.ui.internal.chart depends on javax.imageio
• org.eclipse.smarthome.ui.internal.chart depends on javax.imageio.stream
• org.eclipse.smarthome.ui.internal.chart.defaultchartprovider depends on java.awt
• org.eclipse.smarthome.ui.internal.chart.defaultchartprovider depends on java.awt.image

This is a violation of C.1 in the ESH coding guidelines https://www.eclipse.org/smarthome/documentation/development/guidelines.html#c-language-levels-and-libraries.

It might make sense to split the chart support to a separate bundle and mark it with an exception (only working with full JRE).
But then again, there wouldn't be much left in smarthome.ui but the ItemUIRegistry/Provider, which itself depends on Xtext/EMF/etc. and thus isn't really applicable for constraint devices either - this should change in the context of #5337, so maybe it makes sense to wait for these steps.

@svilenvul tl;dr: I would suggest to add an exclusion for this check for this bundle.

Great, I will add it as exception.
