  [OpenMP] Try to embed offloading objects after codegen

Currently we use the `-fembed-offload-object` option to embed a binary
file into the host as a named section. This is currently only used as a
codegen action, meaning we only handle this option correctly when the
input is a bitcode file. This patch adds the same handling to embed an
offloading object after we complete code generation. This allows us to
embed the object correctly if the input file is source or bitcode.

  [OpenMP] Implement dense map info for device file

This patch implements a DenseMap info struct for the device file type.
This is used to help grouping device files that have the same triple and
architecture. Because of this the filename, which will always be unique
for each file, is not used.

  [Clang] Add offload kind to embedded offload object

This patch adds the offload kind to the embedded section name in
preparation for offloading to different kinda like CUDA or HIP.

Depends on D120288

  [OpenMP][NFC] Refactor new driver to be more general

This path refactors the new driver to be less dependent on OpenMP. This
is done in preparation for the new driver to be able to handle other
offloading kinds and compile them together.

  [CUDA] Add CUDA fatbinary magic

Nvidia uses fatbinaries to bundle all of their device code. This patch
adds the magic number "0x50ed55ba" used in their propeitary format to
the list of magic identifies. This is technically undocumented and could
unlikely be changed by Nvidia in the future.
