Reapply: [llvm-objdump] Add support for HIP offload bundles (#140128)

Utilize the new extensions to the LLVM Offloading API to extend to
llvm-objdump to handle dumping fatbin offload bundles generated by HIP.
This extension to llvm-objdump adds the option --offload-fatbin.
Specifying this option will take the input object/executable and extract
all offload fatbin bundle entries into distinct code object files with
names reflecting the source file name combined with the Bundle Entry ID.
Users can also use the --arch-name option to filter offload fatbin
bundle entries by their target triple.
