- Add v8_code_comments to allow runtime-enabled code comments with
  --code-comments
- v8_code_comments is enable by default in debug mode
- Make MacroAssembler::RecordComment helper inlineable to remove
  call and check overheads when v8_code_comments = false
- Make FLAG_code_comments readonly if v8_code_comments = false and
  benefit from dead-code elimination

This saves roughly 5% CompileBaselineVisit time in sparkplug
on a 5MiB JS file.
