Fix for not finding c_pointer_return call from GPU

When a routine called from the GPU invoked the c_pointer_return function defined in chapel/chpltypes.h at main · chapel-lang/chapel · GitHub we run into the following issue.

$CHPL_HOME/modules/internal/ChapelStandard.chpl:24: error: Could not find C function for c_pointer_return;  perhaps it is missing or is a macro?

Fix was to create a device version of this function as suggested by @e-kayrakli
