In order to do offloading compilation we need to embed files into the host and create fatbainaries. Clang uses a special binary format to bundle several files along with their metadata into a single binary image. This is currently performed using the `-fembed-offload-binary` option. However this is not very extensibile since it requires changing the command flag every time we want to add something and makes optional arguments difficult. This patch introduces a new tool called `clang-offload-packager` that behaves similarly to CUDA's `fatbinary`. This tool takes several input files with metadata and embeds it into a single image that can then be embedded in the host. Reviewed By: tra Differential Revision: https://reviews.llvm.org/D125165
