* during `#preExecute` of `elements.create` process is passed to `shape.create` to be reused during `#execute` (there is no `#exeute` for `elements.create` as it only executes other commands during `#preExecute`)
* process must be reused during `#execute` of `shape.create` for `#redo` to work
* refactor implementation
Closes#1439
Inline `ResizeUtil` into behavior to prevent circular depdendency.
It is not being used outside the behavior anyway and uses behavior
internals (lane dimensions).
This ensures our FixHoverBehavior (that ensures we drop onto /
connect to participants, not lanes) does fix the hover element
during *.out, too.
Otherwise there is no way for other behaviors to correctly
remove hover indicators.

* copy references when copying element
* add referenced root element if it doesn't exist
* do NOT add referenced root element if root element with same ID exists

* unclaim ID of deleted shapes and connections
* unclaim ID of referenced processes when deleting participant
* this does NOT ensure we unclaim IDs of elements like DI, events, errors, ...
