dpasukhi bd651bbbd9 0033531: Configuration - Rework DataExchange ToolKits organization 
Integrated DE plugin functionality.
Reworked DE components:
 - TKDESTEP: Handling STEP file format.
 - TKDEOBJ: Handling OBJ file format.
 - TKDEIGES: Handling IGES file format.
 - TKDEGLTF: Handling GLTF file format.
 - TKDEVRML: Handling VRML file format.
 - TKDEPLY: Handling PLY file format.
 - TKDESTL: Handling STL file format.
Reworked DE DRAW components:
  TKXSDRAWSTEP: Container for DE command to work with STEP.
  TKXSDRAWOBJ: Container for DE command to work with OBJ.
  TKXSDRAWIGES: Container for DE command to work with IGES.
  TKXSDRAWGLTF: Container for DE command to work with GLTF.
  TKXSDRAWVRML: Container for DE command to work with VRML.
  TKXSDRAWPLY: Container for DE command to work with PLY.
  TKXSDRAWSTL: Container for DE command to work with STL.
TKXSDRAW rework to be base DRAW plugin to keep DE session and utils.
