Improve performance of DiagramMigrationHook

The DiagramMigrationHook is inefficient for creating transactional
editing domains, which is very costly as these domains install adapters
to each object. The DiagramMigrationHook now creates a new transactional
editing domain for each diagram and disposes it again.

Instead the editing domain should only be created if needed and be
reused across migrating all diagrams.
