Subject: [PATCH] Make enhanced nav much more conservative, and better handle
 redirections (#50551)

This PR makes enhanced navigation/forms **much** more conservative:

 * For links, enhanced nav remains on by default, but:
   * It's now easy to turn it off or back on hierarchically or on a per-link basis using a `data-enhance-nav` attribute in HTML.
   * If the destination turns out to be a non-Blazor endpoint, enhanced nav will not apply, and the client-side JS will retry as a full page load. This is to ensure we don't confuse other pages that aren't designed to be patched into an existing page alongside the Blazor JS logic.
 * For posts, enhanced nav is now off by default
   * You turn it on by adding `data-enhance` to the form element or `Enhance` if it's an `EditForm` (they're equivalent). This is nonhierarchical since it's not desirable to enable this globally.
   * If the destination turns out to be a non-Blazor endpoint, enhanced nav considers this an error (same reason as for links above). But unlike with links, form posts *won't* retry since it's not safe to do that for POST requests. Developers shouldn't enhance forms that post to non-Blazor endpoints.
 * Redirection handling is much more comprehensive
   * This is way more tricky than I expected. Allowing for combinations of GET/POST, enhanced nav, streaming, Blazor and non-Blazor endpoints, internal and external redirection destinations turns out to break down into 16 separate cases, which you can find [listed in this E2E page](https://github.com/dotnet/aspnetcore/pull/50551/files#diff-477ec16959ae9dddaca3e76e1e40c4d70147210d0fde068357d9ad3e74896337).
   * 15 of those 16 cases now work automatically without errors. The remaining case is "form with enhanced nav does POST to a non-Blazor endpoint which redirects to an external URL", which cannot be supported without having some global server-side logic for all endpoints (not just Blazor ones), so that case explicitly throws a clear error telling the developer not to apply enhanced nav to forms that go to non-Blazor endpoints that redirect to external URLs.
   * There are various subtleties about making the "Back" button work correctly after these enhanced redirections, but I think all of them are covered properly now. The E2E cases all validate clicking "Back" afterwards.
   * Previously it was possible for an internal URL to redirect to an external URL that enabled CORS for your site, and then we would have received and merged that external content into your page. That's no longer the case since we now put `no-cors` on the fetch request, so it should now be impossible to receive content from an external origin (and it falls back on retrying as a full-page load for GET, or an error with a clear message for POST).
 * Disclosure of redirection URLs is now avoided.
   * Previously, for external or streaming redirections, we told the client-side JS code which URL to redirect to. That disclosed more info than a `fetch` normally would. As of this PR, the URL is data protected so all the client can do is navigate to an endpoint that issues a real 302 to the real URL. As such JS no longer has access to any more info than it normally would with a `fetch`.

With all this, it should be much less likely for enhanced nav/redirections to run into incompatibility issues. And much easier for developers to disable it for whole regions in the UI if they want.

+<h2>Enhanced nav to non-Blazor endpoint cases</h2>
+<p>
+    In these cases we can't rely on the server doing anything special to participate in the process.
+    The server is just going to return a regular 302, not any special signal. If the target URL is internal,
+    the "fetch" request will follow it automatically so it just works. If the target URL is external, the
+    "fetch" gets an opaque response, and so if it's a GET we'll follow by retrying, or if it's POST
+    we have to just fail because we can't safely retry.
