misc: Replace type_traits.hh XX::value with XX_v.

Browse Source 
Now that we're using c++17, the type_traits with a ::value member have
a _v alias which reduces verbosity. Or on other words

std::is_integral<T>::value

can be replaced with

std::is_integral_v<T>

Make this substitution throughout the code base. In places where gem5
introduced it's own similar templates, add a V alias, spelled
differently to match gem5's internal style.

gem5: :IsVarArgs<T>::value => gem5::IsVarArgsV<T>
