Doug Parker 160dee33d7 fix(@schematics/angular): don't show server routing prompt when using browser builder
The new routing APIs don't support `browser` builder, but calling `ng add @angular/ssr` with a `browser` builder would still prompt the user to add them. If the user said "Yes", it would actually ignore that answer and not enable the new APIs.

With this change, `ng add @angular/ssr` when using `browser` builder does not show the prompt and assumes the answer is "No". It also throws an error if the user runs `ng add @angular/ssr --server-routing`.

I'm not aware of a built-in prompting mechanism in schematics beyond `x-prompt`, which can't be used here, so instead I just called Inquirer directly. Unfortunately testing the prompt is a little awkward, as Inquirier does not provide useful APIs in this space. I evaluated `@inquirer/testing`, but ultimately decided that was more intended for testing custom Inquirer prompts, not mocking usage of standard prompts. Schematics APIs do not provide a useful way to inject additional data like a mock, so instead I had to do this through a `setPrompterForTestOnly` function. I'm not a huge fan of it, but I don't see a more straightforward way of solving the problem.
