New demo mode and local mode reimplementation (#6819)

* feat: demo mode when using local account

* refactor[demo]: do not allow local account download the game and switch game dir when is demo, use DateUtils instead creating another date checker

* fix[demo]: require activity from optifine installer fragment to minecraft downloader verify if is a local account
