Add TM4E source feature group

The TM4E sources were being generated but not added to the simultaneous
releases Update Site. See https://github.com/eclipse/tm4e/issues/252

Having them available on it will ease the debugging of TM4E code when
you have this Update Site on a target platform without needing to add
the corresponding TM4E Update Site and version used to build the
Simultaneous Release.
