feat(extensions): expose ExtensionRegistryObserver events in Session (#25385)

Browse source 
* feat(extensions): expose ExtensionRegistryObserver events in Session

Extensions can be loaded and unloaded for various reasons. In some cases this can
occur by no means of the Electron programmer, such as in the case of chrome.runtime.reload().

In order to be able to manage state about extensions outside of Electron's APIs, events
reloaded to loading and unloaded are needed.

* docs(extensions): elaborate on extension-loaded/unloaded details

* fix: remove scoped extension registry observer

* docs: update extension-unloaded
