android: Add USE_AUTO_STUB setting

Implements the USE_AUTO_STUB setting in the Android frontend:

- Added USE_AUTO_STUB to BooleanSetting enum
- Added UI switch setting with description in SettingsItem
- Added setting to system settings section in SettingsFragmentPresenter
- Added string resources for setting title and description

The setting allows users to toggle automatic stubbing of missing services
and functions, which may improve compatibility at the cost of stability.
