Original change's description:
> [test][d8] Add d8.log.getAndStop helper
>
> The new helper function allows us to write tests for log parsing
> without the need to first generating a log file. This makes it easier
> to spot errors when the log format changes.
>
> - Add d8 global variable
> - Add file_name accessor to Logger and Log classes
> - Change OS::LogFileOpenMode to w+ / wb+
> - Use separate Log::WriteLogHeader method
> - Remove unused logger_ instance variable from Log
>
