Context:
As part of the work on carbonising multi-selects, we need to carbonise the multi-process selection that we use in filters.
Those selections appear in our filter modals when adding more than one process definition to the report.

AT:

• Replace the multi-process selection with the carbon filterable multi select

Testing Notes

• Create a report with more than one process defintion
• Add one of those filters to the report ( date filter, instance state filter, incident filter, instance duration)
• The process selection, should look like carbon element and work as expected
