[PATCH] D98134: [RFC][POC] Introduce callback argument encoding mode into callback metadata

[Shilei Tian via Phabricator via cfe-commits]

We probably don't need the index for `size_t size`. If the `ArgNo` is out of range, we simply return `nullptr`. Besides, CUDA function `cudaLaunchKernel` doesn't have an argument for size as well.
