[TASK] Update to latest class alias loader version

Benefit from several class alias loader package improvements:

* Use alias map API of this package to resolve and add aliases
* Use new option to force initialization of the alias loader to greatly simplify our runtime code
  This option is only evaluated in non composer mode, which is good because we only need it then.
* Adapt to API change, that now the alias loader is never returned from autoload inclusion

Resolves: #68916
Releases: master
