Rollup merge of #121386 - oli-obk:no_higher_ranked_opaques, r=lcnr

test that we do not support higher-ranked regions in opaque type inference

We already do all the right checks in `check_opaque_type_parameter_valid`, and we have done so since at least 2 years.

I collected the tests from https://github.com/rust-lang/rust/pull/116935 and https://github.com/rust-lang/rust/pull/100503 and added some more
