panfrost: Adds Bifrost shader disassembler utility
This code is stable and can live upstream independently while the rest of the Bifrost stack comes up. v2: Added a verbose flag to hide away some of the more verbose features that nobody really needs [The Bifrost disassembler is written by Connor Abbott, Lyude Paul, and Ryan Houdek.] Reviewed-by: Alyssa Rosenzweig <alyssa@rosenzweig.io>
