LanguageClient: move capabilities widget to inspector

The capabilities are not changeable for the user, but only there to
check whether a server is capable of a specific task. This will also
allow us to have more specialized settings widgets for specific servers
like for the java language server without the need to add the
capabilities to each of those special widgets.

Also add the dynamic capabilities to the widget so users have a complete
overview of the capabilities.
