refactor(console): accept format args directly in console_writeln! macros

Eliminate the nested &console_format!(...) boilerplate at every call site
by teaching console_writeln!, console_write!, console_writeln_error!, and
console_write_error! to accept a format literal + variadic args directly,
matching the println!/eprintln! ergonomics. Propagate the format string
span into generated code so rustc errors point to the right location.
