Migrate detection reference transforms to `torchvision.prototype.transforms`

[pmeier]

In our detection references we have a couple of transformations that can handle images and bounding boxes simultaneously:

• RandomPhotometricDistort port RandomPhotoMetricDistort to prototype transforms #5663
• RandomZoomOut port RandomZoomOut from detection references to prototype transforms #5551
• RandomIoUCrop @vfdev-5 [proto] Ported RandomIoUCrop from detection refs #6401
• ScaleJitter @pmeier port ScaleJitter from detection reference to prototype transforms #6411
• FixedSizeCrop @pmeier port FixedSizeCrop from detection references to prototype transforms #6417
• RandomShortestSize port RandomShortestSize from detection references to prototype transforms #6418
• SimpleCopyPaste @vfdev-5 [proto] Ported SimpleCopyPaste transform #6451

They never made it into torchvision.transforms since have a different call signature than all other transforms there. Now that torchvision.prototype.transforms support simultaneous transforming of multiple types, we can migrate them.
