Bug 569421 - Adds com.ibm.icu to org.eclipse.rcp feature

Modern e4 RCP application do not require com.ibm.icu anymore since
databinding made it optional.

As JDT still needs it, it must be contributed via another feature for
the IDE. Also some text plug-ins still  use it, so we should contribute
it via the org.eclipse.rcp feature as some e3 RCP applications may
require it.
