Rollup merge of #111853 - compiler-errors:opaque-check, r=oli-obk 
Check opaques for mismatch during writeback

Revive #111705.

I realized that we don't need to put any substs in the writeback results since all of the hidden types have already been remapped. See the comment in `compiler/rustc_middle/src/ty/typeck_results.rs`, which should make that clear for other explorers of the codebase.

Additionally, we need to do some diagnostic stashing because the diagnostics we produce during HIR typeck is very poor and we should prefer the diagnostic that comes from MIR, if we have one.
