Type of parameter in constructor of class __transform_functor

[SergeyKopienko]

Not quite understood why the constructor class __transform_functor is implemented not for r-value type of parameter :

oneDPL/include/oneapi/dpl/pstl/utils.h

Line 271 in 4497b15

explicit __transform_functor(_Pred __pred) : _M_pred(::std::move(__pred)) {}

In all use cases we move parameter into it:
https://github.com/search?q=repo%3Auxlfoundation%2FoneDPL+%3A%3A__transform_functor&type=code

So I mean may be better to implement it like we did for __transform_if_unary_functor :

oneDPL/include/oneapi/dpl/pstl/utils.h

Line 305 in 4497b15

explicit __transform_if_unary_functor(_UnaryOper&& __op, _UnaryPred&& __pred)

Example - https://godbolt.org/z/aKG4qdhjr, case 4 and 8

UPD: last modification has been made in the PR #1233, but I think not till the end.
