Decouple Core library from Microsoft.AspNetCore.Components.Web

[VladislavAntonyuk]

The core library should be independent of the framework (shouldn't have dependencies if possible). Extract dependant code to the separate project.

Benefits:

• easy implement different renderers for other platforms - like native Android or iOS (see example: https://github.com/VladislavAntonyuk/Blazor.Diagrams/tree/xamarin)
