This patch adds the necessary changes required to bundle and wrap HIP
files. The bundling is done using `clang-offload-bundler` currently to
mimic `fatbinary` and the wrapping is done using very similar runtime
calls to CUDA. This still does not support managed / surface / texture
variables, that would require some additional information in the entry.

One difference in the codegeneration with AMD is that I don't check if
the handle is null before destructing it, I'm not sure if that's

With this we should be able to support HIP with the new driver.

Depends on D128850 <https://reviews.llvm.org/D128850>
