feat(views): Add FilterSet support to BulkRenameView

Allow passing a FilterSet to BulkRenameView for consistent behavior with
BulkEditView and BulkDeleteView. Enables the
"Select all N matching query" functionality to expand across the full
queryset. Updates logic to handle PK lists appropriately when editing
all matched objects.

Fixes #20389
