We could potentially merge these all into some generic attribute since they all do the same thing on a conceptual level. The unique thing about the existing `amdgpu_kernel` and corresponding `nvptx_kernel` is that they don't rely on the language options like `SYCL` or `CUDA`. Though, semantically those are definitely involved because the kernel itself is only meaningful to whatever runtime is going to load it (e.g. CUDA or HSA) but we can probably consider that separately to the compilation itself and just think of these as calling conventions.
