Auto merge of #126623 - oli-obk:do_not_count_errors, r=davidtwco

Replace all `&DiagCtxt` with a `DiagCtxtHandle<'_>` wrapper type

r? `@davidtwco`

This paves the way for tracking more state (e.g. error tainting) in the diagnostic context handle

Basically I will add a field to the `DiagCtxtHandle` that refers back to the `InferCtxt`'s (and others) `Option<ErrorHandled>`, allowing us to immediately taint these contexts when emitting an error and not needing manual tainting anymore (which is easy to forget and we don't do in general anyway)
