feat(ssr): adds server cookie output via response

[blakeoxx]

This brings the fix/feature completed in #315 to the v18 codebase and resolves #266 . It increases the SsrCookieServices ability to use the request and response objects provided by Express to read and write cookies on the server side. This also means that cookies written during SSR will be returned to the client in the response headers.

This PR also includes less refactors than the previous one, per maintainer request. The only refactors included in this PR were strictly necessary for enabling this feature.

When is this going to be merged? Seems like this is capable of solving some significant challenges.

@blakeoxx I tried this and didn't work as expected. For example, setting cookie in SsrCookieServices using the code does not set it. Do you have an example where it shows this code working?

@pavankjadda try out this test repo: https://github.com/blakeoxx/ngx-cookie-service-18-test. You can build and start the project with npm run build followed by npm run serve:ssr:ssr-cookie-test.

I generated this project with Angular's ng new --ssr command, added the scaffolding to server.ts as outlined in our README, and added a test to the AppComponent which outputs console logs on the server console and client/browser console to confirm the server-side cookie is readable and writable by both platforms. Example output.

Additionally, something I noticed was that NG18's SSR defaults to using prerendering. I had to disable this in the builder architect configuration. It's intended behavior that SSR won't run on prerendered routes and not a bug of this code, but perhaps may be worth calling out in the README.

Let me know if you need anything else or don't see expected results.
