This allows users to specify which process should be used as the parent
process when creating a new process.
Note that this doesn't just trivially pass the handle onward to
PROC_THREAD_ATTRIBUTE_PARENT_PROCESS, because inherited handles must be
valid in the parent process, so if we're changing the destination
process, then we must also change the origin of the parent handles. And,
the StartProcess function must clean up these handles successfully when
exiting, regardless of where the duplication happened. So, we take care
in this commit to use DuplicateHandle for both duplicating and for
closing the inherited handles.
The test was taken originally from CL 288272 and adjusted for use here.
Fixes#44011.
