mdoc: Support for attached events and attached properties

Added AttachedEventReference, AttachedEventDefinition, AttachedPropertyReference, AttachedPropertyDefinition (equivalents of Cecil entities)
They are processed as any other Cecil entities
Added check-monodocer-attached-entities integration test
Added DocId support for attached events and attached properties

Closes #63
