I have run into strange problems with reference types sneaking into
templates. Reference types can cause weird errors when passing things
across hosts and devices, and it's best not to let them sneak into an
object like Varient where they become more difficult to check for.
`std::is_trivial` is part of the C++14 specification. However, we have
encountered multiple compilers that purport to implement C++14 but do
not implement `std::is_trivial` and the like checks correctly.
To avoid such issues, only use `std::is_trivial` on compilers that we
have tested to support it.

They were meant to replace `make_ImplicitFunction*Handle` classes, but
they don't really provide any interesting functionality and are not
backward compatible in any case. So just get rid of one more thing we
don't need to support.
It is possible for a transport to return a reference to an object.
At some point, however, the object has to be potentially copied
to a different memory space to be used in the execution environment.
This was getting fouled up because the reference type was being
captured. Instead, remove any references from the object.
The GCC 7 compiler on summit was failing to compile all of the
code. The problematic parts involved using lambda functions.
I think the problem is that the compiler has a bug where it
has a problem resolving the type of variables captured by
reference. The problem seems similar to this bug reported
to Kokkos:
https://github.com/kokkos/kokkos-kernels/issues/349
Solved the problem by removing the lambdas with either a
named method or just inline code.
I suspect the problem arose (without anyone's knowledge) with
MR !2331, which moved VTK-m to C++14. This GCC error seems to
happen with C++14 but not C++11. (The features of lambdas changed
between these two versions of C++.)

Unfortunately, this introduces a backward-incompatible change with the
filters that use ImplicitFunctions. Before, they would get an
ImplicitFunctionHandle. This class is deprecated, and there is no easy
way to get back the actual type of implicit function stored in it.
