LOG: [RemoveDIs] Load into new debug info format by default in llvm-dis (#86276)

Directly load all bitcode into the new debug info format in llvm-dis.
This means that new-mode bitcode no longer round-trips back to old-mode
after parsing, and that old-mode bitcode gets auto-upgraded to new-mode
debug info (which is the current in-memory default in LLVM).
