Razor Toolbox Completeness

Some ideas from other issues:

1. [x] https://github.com/dotnet/razor/issues/8792 All HTML based components
2. All SDK Blazor Components
3. For hybrid projects, reasonable analogous components: i.e. MAUI, WPF and Windows Forms
4. Build my own component library and add these to the tree easily when I import my own component library project into a solution (Package Reference)
5. Be able to drag my own components from a Blazor component library from a project into the toolbox (Project Reference)
6. Anything to do with data connectivity e.g. Azure SQL database/Cosmos DB/APIs
7. An area for most recently used components for Blazor projects
