  [lldb] Add plugin for Clang offload bundle object container (#222362)

## Summary

Clang supports embedding binaries using the clang offload bundler:

https://clang.llvm.org/docs/ClangOffloadBundler.html

This patch creates an ObjectContainer plug-in that allows us to get the
contained binaries within any executable.

### why we need this? 
AMD/HIP host binaries may contain a .hip_fatbin section holding a Clang
offload bundle with one or more AMDGPU ELF code objects, typically for
different GPU architectures. Each ELF code object can contain multiple
ml kernels.


### Test 

Added tests for the logic.


NOTE: Caching was intentionally left out to keep the upstream initial
implementation simple; i will add it as a followup.
