Auto merge of #67808 - Marwes:projection_normalization_recurse, r=nikomatsakis

perf: Don't recurse into types that do not need normalizing

A bit speculative at this stage but profiling shows that type folding
takes up a substantial amount of time during normalization which may
indicate that many types may be folded despite there being nothing to
normalize
