EDM Device Test Fix, main branch (2024.02.05.)

Fixed "variable shadowing" warnings coming from MSVC. Things like:

[ 93%] Building CXX object tests/cuda/CMakeFiles/vecmem_test_cuda.dir/test_cuda_edm.cpp.obj

Since these only show up with CUDA and SYCL on Windows, the CI is blind to it. The HIP tests are not processed by MSVC ever, but it would've been silly not updating that code as well. 🤔
