Cycles X: Reduce OIDN memory usage with multi-device render

Allow OIDN to modify render buffers in-place, without allocating
extra temporary buffers.

Currently memory is only saved for non-composited passes (combined,
shadow catcher matte). The composited passes are possible to avoid
memory allocation as well, but requires passing row stride to the
pass accessor which is not yet possible.
