[BUG] Unit tests fault when CUB Cache Disablement is Disabled

[tmartin-gh]

Describe the Bug
Unit tests throw an instance of std::bad_any_cast when compiling with MATX_DISABLE_CUB_CACHE=OFF

Note: Google Test filter = ReductionTestsNumericNoHalfAllExecs/0.Sum*
[==========] Running 1 test from 1 test suite.
[----------] Global test environment set-up.
[----------] 1 test from ReductionTestsNumericNoHalfAllExecs/0, where TypeParam = cuda::std::__4::tuple<unsigned int, matx::cudaExecutor>
[ RUN      ] ReductionTestsNumericNoHalfAllExecs/0.Sum
terminate called after throwing an instance of 'std::bad_any_cast'

To Reproduce

cmake -DCMAKE_CUDA_ARCHITECTURES=80 -DCMAKE_BUILD_TYPE=Debug -DMATX_BUILD_EXAMPLES=ON -DMATX_BUILD_TESTS=ON /nfs/scratch.timothym_ate_1/MatX3 -DMATX_DISABLE_CUB_CACHE=OFF

make -j matx_test

./test/matx_test --gtest_filter="ReductionTestsNumericNoHalfAllExecs/0.Sum*"

    Cleaning up non-const operator() to avoid code duplication (#769)

Expected Behavior
Unit tests should all pass.

Note, even compiling with MATX_DISABLE_CUB_CACHE=OFF fails at the moment. The reproducer above has all .cu files in test/CMakeLists.txt commented out except for main.cu and ReductionTests.cu. If all .cu files are included, then we see many compiler errors such as
