Ios13: Fixing broken launch on simulator target

With Xcode 11 RoboVm can’t deploy to simulator anymore. It fails with:

simlauncher[70781:19762861] *** Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘+[DVTSimulatorApplication simulatorApplicationForDevice:]: unrecognized selector sent to class 0x1077a3590’

simlauncher was borrowed from MOE project and internaly build around tonns of hacks, and its hard to keep maintain it this way.
Meanwhile Apple provides simctl tool allong with Xcode and its functionality quite enough for RoboVm needs.

PR402 deliver migration to simctl and introduces following changes:

• rmeoves simlauncher;
• boots simulator if required with simctl boot;
• deploys application with simctl install;
• and launches it with simctl launch.

It works for me with Xcode11 and also has to be backward compatible.
