Rollup merge of #135816 - BoxyUwU:root_normalizes_to_goal_ice, r=lcnr

Use `structurally_normalize` instead of manual `normalizes-to` goals in alias relate errors

r? `@lcnr`

I added `structurally_normalize_term` so that code that is generic over ty or const can use the structurally normalize helpers. See `tests/ui/traits/next-solver/diagnostics/alias_relate_error_uses_structurally_normalize.rs` for a description of the reason for the (now fixed) ICEs
