exo: add usb3 force enable support

Browse Source 
Like the other configs, it can be read from system_settings.ini and be set.

Additionally a new `usb3force` key was added to allow user to override and enable/disable that setting via a boot entry.
This allows for fast (re)boot into an entry that disables that (important because of the huge interference that USB3 creates to Bluetooth and WiFi 2.4GHz).
