[Blazor] Allow to reference constant field in @page directive

[xperiandri]

Is your feature request related to a problem? Please describe.

In order to not forget to change all the occurrences of some route when it changes I would use a constant field. However, Blazor does not allow to reference a constant field in @page directive like I can do in RouteAttribute that it produces.

Describe the solution you'd like

Thanks for contacting us, @xperiandri.
You can simply use the @attribute [Route(MyConstants.FixedRoute)] as an alternative to using @page.
