[llvm] [NFC][llvm-objdump] Add quiet disassembly (PR #139931)

[Petr Hosek via llvm-commits]

I'd prefer instead adding an extra argument to `disassembleObject` (and other functions like `dumpELFData`) representing the output stream.

`--call-graph-info` implementation could then pass `null()` as the argument when invoking `disassembleObject`.
