Use "Ex"-versions of WaitForSingle/MultipleObject(s) where possible

Not only should using the "Ex"-versions be the rule and not the
exception on Windows, but it's only the only way to share as much
code as possible between Desktop Windows and WinRT (which is pushed
by Microsoft a lot). The current rule of Desktop and WinCE vs WinRT
does not make a lot of sense any longer, as WinCE is getting less
and less important. By moving these #ifdefs in favor of WinRT,
WinCe code might be removed easier in the future.
