[oneDPL][ranges] Rearrange the range algorithms

[akukanov]

As more parallel range algorithms have been added to the specification, it makes sense to reconsider the grouping, specifically for mutating algorithms, combining together those with similar semantics.

After the change, there will be the following groups of algorithms:

• whole sequence operations: (all|any|none)_of, count[_if], for_each, copy, move, fill, swap_ranges
• minimum and maximum: no changes
• element search: no changes
• sequence search and comparison: no changes
• sequence transformation: transform, replace*
• sequence reordering: shift*, rotate*, reverse*
• sequence filtering: copy_if, remove*, unique*
• sorting, merge, and heap: no changes
• set operations: no changes
• partition operations: no changes
• uninitialized memory algorithms: no changes

The patch is completely editorial, as it only moves the declarations and does not introduce any API changes. It is probably best reviewed by individual commits.
