## Bug
Fixes: #31993
* Remove the simple component checking in middleware ssr
* Leverage existing components checking for Component / App / Document, if any of these component is not valid react type or is undefined nextjs will error in dev mode with redbox. Like above.

### Changes
* node server and webpack should share the same logic: auto detect react 18 and enable `reactRoot`
* fallback `_error` should use functional document if concurrent rendering is enabled
### Test
* Remove the hard code `reactRoot: true` in test suite
* Test some react-18 test suite with nodejs runtime
Cleans up the code of the middleware SSR loader and the web server. Currently the page components and render options are provided to the server via `globalThis` which is not ideal.
Instead we can inject `extendRenderOpts` and `loadComponent` to the web server. Since this is the the minimal mode and we'll need to handle `?flight` requests, we update the server render opts upon `updateRenderOpts` (In the future this should be changed to be passed to `requestHandler` to avoid race conditions).
Currently, we can't fully get rid of the `__server_context` global as we call `getBuildId` in the base server constructor.
