This does the following changes: * Show info "warnings" in modifier too. Previously those were skipped. The different behavior of info/warning/error messages causes confusion. * Add a new `Warnings` panel that only shows when there are warnings. In its title, it shows how many warnings there are. * In the panel, warnings are sorted by severity and alphabetically. Pull Request: https://projects.blender.org/blender/blender/pulls/128395
