Using split copy to fix metal issue on uploading texture from an unpacked buffer

When uploading textures from an unpack buffer, some drivers count an
extra row padding when checking if the pixel unpack buffer is big
enough. This will generate error about totalUsedBytes is larger than the
buffer.

Using split copy to take care of the last row of the unpack buffer will
workaround this issue.
