Load FAP files through the plugin and games menu if possible

[YoshiFan501]

Is your feature request related to a problem? Please describe.
After updating to the ELF loader, the games and plugins on external are only openable after opening the ELF Loader, unlike all of them being organized under games or plugins.

Describe the solution you'd like
Allow the Plugin and Games menu to show or load .FAP files when put into the application.fam file under apps/meta. (when I compiled the firmware myself with them readded to the file, it has both internal and externals on the flipper)

Describe alternatives you've considered
Changing Plugins and games to their own ELF Loader programs and seperate folders in the sdcard for easier organization

Additional context
N'A

This would be great... wouldn't be attempted till FAPs are worked into main... feel free to develop :)
