Rollup merge of #118888 - compiler-errors:uplift-more-things, r=jackh726

Uplift `TypeAndMut` and `ClosureKind` to `rustc_type_ir`

Uplifts `TypeAndMut` and `ClosureKind`

I know I said I was just going to get rid of `TypeAndMut` (https://github.com/rust-lang/types-team/issues/124) but I think this is much simpler, lol

r? `@jackh726` or `@lcnr`
