Revamp acton(c) debug & verbose output

[plajjan]

• "verbose" is better than "debug" - we used to have both and it wasn't very structured. I merged them into a single --debug flag - that was a mistake, we should flip back to verbose
  • we can compile and optimize for debug / development builds - avoid confusion around "debug" by calling our verbose output options to the compiler something with "verbose"
• our debug verbosity in actonc also enables verbose output from zig - this leads to VERY verbose output
• we want to separate these into two args, --verbose and --verbose-zig, most of the time we are only interested in one or the other
• print messages to stderr
