Remove Tycho specific dev entry support

Tycho currently contains support for pde-dev entries explicitly stated
to "support running Tycho its from workspace".

As Tycho is now "pure maven" this is no longer required (and has never
worked well). The features requires some special setup, depends on
deprecated Maven API and even references no longer existing Tycho-code,
this is now removed to lower the barrier for mvn4 transition.
