  Allow the dumping of .dwo files contents to show up when dumping an executable with split DWARF. (#66726)

Allow the dumping of .dwo files contents to show up when dumping an
executable with split DWARF.

Currently if you run llvm-dwarfdump on a binary that has skeleton
compile units, you only see the skeleton compile units. Since the main
binary has the linked addresses it would be nice to be able to dump
DWARF from the .dwo files and how the resolved addresses instead of
showing the address index and "<unresolved>" in the output. This patch
adds an option that can be specified to dump the non skeleton DIEs named
--dwo.

Added the ability to use the following options with split dwarf as well:
  --name <name>
  --lookup <addr>
  --debug-info <die-offset>
