- allows restricted evaluation to specific coupled patch types.
  Code relocated/refactored from redistributePar.

STYLE: ensure use of waitRequests() also corresponds to nonBlocking

ENH: additional copy/move construct GeometricField from DimensionedField

STYLE: processorPointPatch owner()/neighbour() as per processorPolyPatch

STYLE: orientedType with bool cast operator and noexcept
