COMP: add <numeric> to stdFoam.H

- useful to have std::reduce(), std::transform_reduce() available in more places, so treat like <algorithm> and include in "stdFoam.H" STYLE: add 'stricter' detection markers for cast of SubList to List etc. STYLE: remove 'const' qualifier from Foam:one/Foam::zero (in Field)
