ios: preliminary support for ios

first work in progress support for ios
* separate iosTool using xml communication used for device info and run
* iossim tool to handle the simulator
* debug prepared but not working
* separate gcc toolchain detection fix for simulator

1) add a QT built for ios
2) open a project, for example qtbase/examples/widgets/animation/animatedtiles/animatedtiles.pro
3) build/run...
