The `vtkm_unit_tests` function in the CMake build now allows you to specify which files need to be compiled with a device compiler using the `DEVICE_SOURCES` argument. Previously, the only way to specify that unit tests needed to be compiled with a device compiler was to use the `ALL_BACKENDS` argument, which would automatically compile everything with the device compiler as well as test the code on all backends. `ALL_BACKENDS` is still supported, but it no longer changes the sources to be compiled with the device compiler.
