feat(browser): Add outgoingRequest context to fetch errors

[mydea]

For now, this only adds method and url fields.

Implements #15846 for fetch only. This is probably the most important, not sure if we also want to add this to XMLHttpRequest handling (it is possible there but a bit trickier, as we'd need to parse method/url out of the request etc)

@mydea (once you're back) Is this still something we wanna pursue? PR LGTM in general but asking since it's been open for a while.

hmm good question, maybe it's worth to double check if this still makes sens (I believe yes but to be sure)!
