Unrolled build for rust-lang#140559

Rollup merge of rust-lang#140559 - rperier:type-ir-to-type-middle, r=compiler-errors

Removing rustc_type_ir in the rustc_infer codebase

cc rust-lang#138449

This is a second refactoring of rustc_type_ir to use rustc_middle instead, this time that's for rustc_infer
