Kenneth Moreland 05bf2e4518 Remove TestingFancyArrayHandles.h
This header file contained tests for a bunch of fancy array handles so
that they could be compiled for each device. These tests were bunched
together because they were replicated for each device implementation,
which was a hassle. However, having a bunch of tests crammed together is
problematic for a number of reasons.

The new testing no longer has a need to make a separate test for each
device. Thus, the tests for the individual devices are removed, and the
tests are split up and added to the basic vtkm_cont tests. In some
cases, individual tests already existed there as well (probably because
the developer did not see the test).
