Auto merge of #15559 - Veykril:builtin-format-args, r=Veykril
Implement builtin#format_args, using rustc's format_args parser `format_args!` now expands to `builtin#format_args(template, args...)`, the actual expansion now instead happens in lowering where we desugar this expression by using lang paths. As a bonus, we no longer need to evaluate `format_args` as an eager macro which means less macro expansions overall -> less cache thrashing!
