[range.adaptors] Move [range.chunk.by] after [range.chunk]

Also "As const view" could move up next to "As rvalue view".

@jensmaurer Do you think those are useful rearrangements?

[tkoeppe]

And we can move "slide view" up to just after the "adjacent" views, since they both produce "subranges" rather than elements, i.e. elements of the original range are seen repeatedly.

[JohelEGP]

There's room for further more improvement. Here's my compiled suggestion.

• Transforms: (All, as rvalue, as const, transform, common, elements)
  • (All, common) change the input range's interface only.
  • (As rvalue, as const, transform, elements) transform the elements.
• Subsets: (Filter, take, drop, counted, stride)
• Subranges: (Split, adjacent, chunk, slide)
• Packers: (Zip, cartesian product, enumerate)
• Join, reverse.

Generally agreed here; maybe "transforms" -> "transformations".
