Continue investigation of DetoxHelper

[LeoNatan]

iOS presents challenges to some permission modifications on the fly. Right now, DetoxHelper supports on the fly modification of notification permissions, but other permissions (set in TCC) are not supported due to iOS limitation. Need to investigate here what can be done to workaround this. It is worth noting that in iOS, when these same TCC permissions are modified in the settings app, iOS kills the process. So this may not be possible.

DetoxHelper is architectured to expose its functionality through iOS extensions. These extensions can then be triggered from the Detox framework, alleviating the need to resign the user's app bundle.

DetoxHelper is simulator-only and is signed with Apple-private entitlements.
