COMP: Fix "unused-local-typedefs" warnings

This commits fix warnings discovered while compiling Slicer. At the
exception of the change to "itkLinearInterpolateImageFunction.h", all
update consisted in removing line defining unused local typedefs.

Within "itkLinearInterpolateImageFunction.h", the "itkConceptChecking"
header has been included to make use of the itk::Concept::Detail
and get ride of warning for traits. Similar approach has been used in 8329f68.
