  [CUDA][HIP] Fix host/device attribute of builtin (#138162)

When a builtin function is passed a pointer with a different
address space, clang creates an overloaded
builtin function but does not copy the host/device attribute. This
causes
error when the builtin is called by device functions
since CUDA/HIP relies on the host/device attribute to treat
a builtin function as callable on both host and device
sides.

Fixed by copying the host/device attribute of the original
builtin function to the created overloaded builtin function.
