Feature Request - Option for Blazor's `NavigationManager.NavigateTo` to halt additional processing

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

I'm trying to handle a default route parameter. When no route parameter is given, I'd like to call `NavigationManager.NavigateTo` to add a default route parameter to the URI. Doing so will allow the appropriate `NavLink` to be given the `active` class.

Alternatively, if `NavLink` can be given 2 Match options, that would also solve it.

### A clear and concise description of what the problem is.

The issue with calling `NavigationManager.NavigateTo` is that processing continues for a bit. For example, if I call `NavigationManager.NavigateTo` in `OnInitialized`, `OnParametersSetAsync` will still be called, which can cause an error or perform unnecessary work that the user must wait on.

### Describe the solution you'd like
Either `NavigationManager.NavigateTo` could halt immediately and perform the route navigation, or `NavLink` could accept an additional `Match` value.
