When using a tool, for each diagram element on the diagram the method FilterService.sortFilters is called. This produces performance issues with big diagram.

The solution is to sort activated filters each time a new one is added only once.

Steps to reproduce:

Using family exemple, put a breakpoint in FilterService.sortFilters.
Then use the man creation tool in a diagram to add a new man.

KO you see that the sorting method is called for each diagram element in calling stack of org.eclipse.sirius.diagram.ui.business.api.helper.graphicalfilters.CompositeFilterApplicationBuilder.computeCompositeFilterApplications()
