basichost / blankhost: wrap errors

[Wondertan]

The goal here is to improve the experience of working with errors returned by the Host. With the current state, it's PITA to debug exactly what went wrong during a stream open and this feat attempts to solve it.

• Inspired by errors in std net.
• I wanted to improve the RoutedHost as well, but I will wait until you migrate to v1.20, as I need errors.Join
• I am open to any other suggestions on how to make this even better
• Can we include this in 0.28? 🙏🏻 🙏🏻 🙏🏻

Closes #2334

I’m ok with the error wrapping changes introduced here. I’d like to be a little bit more careful about introducing a new error type here. Not saying that it’s a bad idea, but I’d prefer to have an issue and an API discussion first.

My toxic trait is coming up with contributions out of nowhere 😄.

Ok, let's make an issue!

Any chance you can take a look at this?

I already reviewed this PR. Let me know once you've updated it.

[Wondertan]

Ok, it wasn't clear whether changes were requested or not

Updated to keep wrappings only

... and so on for the other errors.

A user would usually wrap the error with "failed" or the log would also say that error, but I don't feel strongly about it, so applied.

@Wondertan Any reason you only changed ~half of the error messages?
