Micha Reiser 678b0c2d39 [red-knot] Resolve Options to Settings (#16000)
## Summary

This PR generalize the idea that we may want to emit diagnostics for 
invalid or incompatible configuration values similar to how we already 
do it for `rules`. 

This PR introduces a new `Settings` struct that is similar to `Options`
but, unlike
`Options`, are fields have their default values filled in and they use a
representation optimized for reads.

The diagnostics created during loading the `Settings` are stored on the
`Project` so that we can emit them when calling `check`.

The motivation for this work is that it simplifies adding new settings.
That's also why I went ahead and added the `terminal.error-on-warning`
setting to demonstrate how new settings are added.

## Test Plan

Existing tests, new CLI test.
