WinRT: Fix argument handling on Windows 10

Browse Source 
The Windows 10 CRT does not export __getmainargs(), so we need to move
to GetCommandLine like on WinCE and desktop Windows. As CommandLineToArgv
is not available, the command line is split according by spaces, allowing
for quotes (and quote escaping) around arguments.
