[FEAT] Render the Compensation Marker of an activity

[csouchet]

Is your feature request related to a problem? Please describe. Render BPMN Element - depends on #347

• The marker for a Task that is used for compensation MUST be a pair of left facing triangles (like a tape player “rewind” button).

• The Compensation Marker MAY be used in combination with the loop marker or the multi-instance marker.

• All the markers that are present MUST be grouped and the whole group centered at the bottom of the shape.

Note for implementation See the development documentation for details.

Please reuse the icon used for the Compensation Event.

Notes

• prior implementing this feature, some general improvements applying to markers must be implemented first. See #3146
