[74625] Make project hierarchy collapsable in the global project selector (#23137)

* Use new async FilterableTreeView for global project selector

* Remove replaced angular component

* Fine tune sorting and expansion state of the new project selector

* Update primer to 0.86.1

* Add workspace information and filter results hierarchy information to project selector

* Include review feedback: Harmonize I18n keys, fix visible scope, use guarded local storage

* Add a turboFrame in the project select overlay to only load the projects when it is actually opened

* Restore BIM tab styles which were broken for a while already but the new project selector changes made it so bad that the test broke because the plus icon was overlapping the checkbox

* Clarify spec expectation
