src: add support for ETW stack walking
V8 supports native stack walking in Windows by providing JIT code
information to ETW (Event Tracing for Windows). But the option to
enable it is not exposed in NodeJS.
Just add command line (and environment variable) support for
--enable-etw-stack-walking, that maps to V8 option of the same name.
