Previously, the vtkm_unit_tests CMake function added a "NONE" argument
to the test when no device was specified. However, the correct thing to
do is to add no argument. Fixed this so that strict parsing of the test
arguments works.
Consumers of VTK-m when enabling of dropping of unused functions
will see VTK-m functions dropped. Previously this didn't happen
as VTK-m didn't build object files with the correct flags for this.
By allowing the linker to remove unused symbols we see a significant
saving the file size of VTK-m tests, examples, and benchmarks.
An OpenMP build of the tests and benchmarks goes from 168MB to
141MB which is roughly a 16% filesize reduction.
Initially I had presumed that these changes would increase link times.
But in measurements the total wall time for compilation of VTK-m has
stayed about the same ( seeing a decrease of 1.5% ). Presumably the
increased computation is offset by the reduction in file writing.
Instead of having to be called for each target you can now
pass multiple targets at once. Do note that if you pass multiple
targets you will need to pass all the sources from those targets
that need to be 'device' compiled.
This is a work around while we wait on requiring CMake 3.15 for all
cuda builds. At that point we can replace this with setting
`requires_static_builds` as part of the EXPORT_PROPERTIES of the
vtkm_cuda target.
This has been tested with the ascent proxy

This was causing issues for downstream users of VTK-m as it exposed
a bug in CM ( cmake#17952 ) where it was evaluating against the set of
enabled languages instead of possible languages.
When both examples and tests are on, there are a few tests created that
will install VTK-m and build the example against the install to make
sure that all expected components are installed. Since it requires the
full compile of a VTK-m application (and some VTK-m applications can
take a while to compile), increase the timeout for these tests.
The timeout is currently set to 10 minutes (600 seconds).

The VTK-m testing infrastructure isn't public facing so it doesn't
need to be installed or clutter the main VTKmWrappers file.
At the same time I have refactored the code to make it clearer
to understand, and remove unused options.
