iOS: Link to the platform plugin and iosmain plugin and define main
Ideally we'd only have to do QTPLUGIN += ios, but this doesn't work as we need to link with the force_load linker option. Even trying to build on QTPLUGIN and then replace the -l line with what we need will fail, as the prl logic in qmake which runs after all the prf files does not know about the force_load option and will then fail to resolve dependencies from the prl file. Since we load the platform plugin using -force_load, there's no need to generate a cpp file that does the plugin import. The main wrapper is not a real Qt plugin, and doesn't have an import function that we can call, so we link it manually instead of relying on QTPLUGIN.
