This commit refactors the `add_offload_test_device_code` CMake function to compile device code using the C++ compiler (`CMAKE_CXX_COMPILER`) instead of the C compiler. This change enables the use of C++ features, such as templates, within device-side test kernels. This will allow for more advanced and reusable kernel wrappers, reducing boilerplate code in the conformance test suite. As part of this change: - All `.c` files for device code in `unittests/` have been renamed to `.cpp`. - Kernel definitions are now wrapped in `extern "C"` to ensure C linkage and prevent name mangling. This change affects the `OffloadAPI` and `Conformance` test suites. cc @callumfare @RossBrunton @jhuber6
