Allow to disable touch indicators on IOS

[Gongreg]

We are implementing screenshot tests when running detox, there is a issue that we have to wait 500ms just to be sure that all touch indicators have disappeared. It would be nice to have an option to disable them.

We have the same use-case and would love to be able to disable it.

#751 still needs JS support.
Current state of this PR will allow disabling of touch indicator by adding disableTouchIndicator to launchArgs.
The missing piece currently is a way to preserve launch args and parameters passed to launchApp upon recovery from app crash.
The easiest way of doing it is by saving them inside Device.js and exposing a function (something like getLastLaunchParams()) that will be in app crash recovery.

This is a fairly simple and straight forward solution IMO, other ideas are welcome of course.

BTW,
I would prefer the parameter to be positive instead of negative, enableTouchIndicator, default true/YES.

If it's enabled, the param should be disable. Naming should follow the rules of "what happens if the param is not there".
