Support for `MicroProfile RestClient` CodeAction for referenced interface

Takes a sample:

package org.acme.restclient;

public interface MyService {

}

public class Fields {
 
	@Inject                                          
	@RestClient
	public MyService service1, service2;
}

In this case service1 and service2 have errors because MyService is not annotated with RegisterRestClient.

It should be nice to have a CodeAction triggered from the service1, service2 field which insert RegisterRestClient in the MyService interface.

Start by locating the CodeAction handling for the service1 and service2 fields in the Java language server, then trace how the referenced MyService interface is resolved. The work is complete when invoking the action from either field adds RegisterRestClient to MyService and the resulting diagnostics are cleared.
