Extend LLVM Offloading API for binary fatbin Bundles

  With the intention to provide a common API for offloading, this
  extension to the existing LLVM Offloading API adds support for
  Binary Fatbin Bundles; moving some support from the Clang offloading
  API.  The intention is to add functionality to LLVM tooling for
  Binary Fatbin Bundles in subsequent commits.
