Rollup merge of #100053 - flip1995:clippy_backport, r=xFrednet

move [`assertions_on_result_states`] to restriction

"Backports" the first commit of https://github.com/rust-lang/rust-clippy/pull/9273, so that the lint doesn't go into beta as a warn-by-default lint.

The other changes in the linked PR can ride the train as usual.

r? ``@xFrednet`` (only Clippy changes, so we don't need to bother compiler people)
