Execute EEFViewImpl#initialize() outside of a command

The method only touches EEF-specific models which are not physically
connected to e.g. a Sirius-owned editing domain.

Executing the command on the editing domain's stack offers no benefit in
our particular case: our objects are not inside any resources and do not
have a TransactionChangeRecorder attached. However it triggers all the
command stack's listeners, in particular all GMF actions (when in the
context of a Sirius diagram), who re-compute their enablement status at
significant runtime cost.

Executing the initialization directly significantly improves
performances.
