Andrew Kushnir 478c5ac150 refactor(core): internal tracker of pending tasks during initial rendering (#49576) ...

This commit implements a simple tracker of the pending tasks during initial rendering. The class allows adding and removing tasks from the set. The class also exposes a promise that gets resolved once the last task is removed.

This tracker is needed to keep track of ongoing processes like Router navigation (and potentially HTTP requests) and acts as a signaling mechanism to SSR and hydration that the application is in the "stable" state and a serialization can be performed.

This class would also act as a future replacement for the `ApplicationRef.isStable` for zoneless applications.
