Update the transfer cache check to safely exclude all requests sent with the `withCredentials` flag.
By default, the HTTP transfer cache avoids caching user-specific responses to prevent sensitive data exposure or incorrect caching. While requests with explicit headers like `Cookie` or `Authorization` are excluded by default, requests can also be sent with credentials via the `withCredentials` flag without having those headers explicitly declared on the request object.
To keep user-specific responses from being cached, exclude `withCredentials` requests unconditionally, even when the `includeRequestsWithAuthHeaders` option is set to true.
Treat requests with a Cookie header like other auth-bearing requests and skip TransferCache caching them by default.
This preserves the explicit opt-in path via includeRequestsWithAuthHeaders, adds regression coverage for cookie-bearing requests, and updates the SSR guide to document the behavior.
In this commit, we replace `isPlatformServer` runtime call with the `ngServerMode` in the `transferCacheInterceptorFn` in order to make the functionality tree-shakable between client and server bundles.

Expose `HTTP_TRANSFER_CACHE_ORIGIN_MAP` injection token in public api. This is useful when different origins are used to access the same APIs between server and browser.

This update modifies the transfer cache logic to prevent caching of HTTP requests that require authorization. To opt-out from this behaviour use the `includeRequestsWithAuthHeaders` option in `withHttpTransferCache`
BREAKING CHANGE: By default we now prevent caching of HTTP requests that require authorization . To opt-out from this behaviour use the `includeRequestsWithAuthHeaders` option in `withHttpTransferCache`.
Example:
```ts
withHttpTransferCache({
includeRequestsWithAuthHeaders: true,
})
```

This update enhances the encoding handling of request bodies to generate the necessary cache key for transfer cache functionality.

PR Close#54980
`provideClientHydration()` accepts new `HydrationFeature` : `HttpTransferCacheOptions`.
`withHttpTransferCacheOptions` accepts an option object:
* `includeHeaders` : list of headers entries to keep in the cache with the request
* `filter` a callback to determine if a request should be cached
* `includePostRequests`: to include POST requests in the allowed methods
Implements some of the features requested in #50117

This commit adds support by default for HTTP caching when using `provideClientHydration`. Users can opt-out of this behaviour by using the `withoutHttpTransferCache` feature.
```ts
import {
bootstrapApplication,
provideClientHydration,
withNoHttpTransferCache,
} from '@angular/platform-browser';
// ...
bootstrapApplication(RootCmp, {
providers: [provideClientHydration(withNoHttpTransferCache())]
});
```
PR Close#49699
This commit adds a new option for `provideHttpClient` called
`withHttpTransferCache()`. When this option is passed, requests done on the server are cached and reused during the bootstrapping of the application in the browser thus avoiding duplicate requests and reducing load time.
This is the same as `TransferHttpCacheModule` in https://github.com/angular/universal/blob/main/modules/common/src/transfer_http.ts
