Rollup merge of #104317 - RalfJung:ctfe-error-reporting, r=oli-obk
cleanup and dedupe CTFE and Miri error reporting

It looks like most of the time, this error raised from const_prop_lint is just redundant -- it duplicates the error reported when evaluating the const-eval query. This lets us make `ConstEvalErr` private to the const_eval module which I think is a good step.

The Miri change mostly replaces a `match` by `if let`, and dedupes the "this error is impossible in Miri" checks.
