Remove the `BitIconName` enum from the Bit Componets project

[msynk]

By removing the redundant font files (#2098) it's better to remove the BitIconName enum and its infrastructure from all over the components project and move its functionality to the assets NuGet package. And also it's better to change it to a static class with public static string properties which together with changing the type of Icon parameter in the components to string, can remove the reflection process required to use the enum.
