David Fort e944d8d243 winpr: improve WaitForSingleObject and WaitForMultipleObject with processes
This patch improves waiting on process handles:
* under linux we take advantage of pidfd if available, when it can be used it
allows to have one or more process in the objects that are WaitForMultipleObject-ed.
* the patch also make the code honor the timeout parameter during a WaitForSingleObject and
possibly run completion when WaitForSingleObjectEx is executed with alertable set to true
