* feat: Print FatalError messages using Logger
This makes them appear GHA annotations in CI logs, which makes them easier to spot. I've also added the "cibuildwheel: " prefix to those errors, I think it helps when viewing a log to know which tool is talking to you - it can be difficult to understand with build tools.
* Nicer error message on invalid architecture
* Fix some message formatting and test expectations
