[oneDPL][ranges] Add shift_left and shift_right

[dmitriy-sobolev]

Adding shift_left and shif_right parallel range algorithms into oneDPL specification.

The signatures are good.

However, it looks like the split of mutating algorithms to just "copying" and "in-place" becomes less convenient as we add more algorithms to the list, in particular because pairs of "equivalent" in-place and copy operations become separate.

As the first step towards reworking it, I suggest combining shift and rotate algorithms - both copying and in-place - into a new "Sequence reordering" group. We can later move reverse algorithms there as well.
