add xsbug to XS?

XS has a custom executable for debugging unlike the other engines. What are the thoughts on including it? Seems like a doable PR if I know any objections or constraints.

jsvu is intended to provide JavaScript engine binaries for use on the command-line and with eshost. On first glance, xsbug does not seem to be a separate JavaScript engine, but a separate binary to be used alongside an xs environment. As such I'm leaning towards not doing this, but I'd love to understand your use case better! Can you elaborate? cc @phoddie

Mostly I'm trying to debug things and not just run them ;p , using a version manager is easier than telling peers to build from scratch. d8 ships with this by default https://v8.dev/docs/inspector but other engines might not.
