Use PluginProvidersTrait in BlockLibraryPanel?

Problem/Motivation

In ✨ Manage breakpoints & add viewports switcher Active , we have introduced PluginProvidersTrait to merge logic from ComponentLibraryPanel and ViewportSwitcher.

Proposed resolution

Do we use this trait also in BlockLibraryPanel? The logic here is a bit different but taht could be the opportunity to have a cleaner and more generic logic.
