Support safari webextensions in runtime-js

[Kjoep]

🙋 feature request

Runtime-js currently has specific support for chrome and firefox extensions. It has logic to generate a url relative to the bundle root. For Safari this logic is missing, and parcel generates non-functional URLs. (could be considered a bug, depending on how you look at it)

🤔 Expected Behavior

When accessing assets in a safari extension, URLs should be formed correctly by getBundleUrl/getBaseUrl/getOrigin.

😯 Current Behavior

URLs generated by getBundleUrl/getBaseUrl/getOrigin do not get transformed and are not generally resolvable in a safari extension.

💁 Possible Solution

Adapt the regex in bundle-url.js to also support safari extensions.
I wrote a fix here: 6b82317

Feel free to make a PR with that commit! We have only tested that regex on Chrome and Firefox extensions, but I think pretty much every major browser beyond Firefox uses Chromium at this point so they all use chrome-extension. I guess Safari made their own implementation though.
