Rollup merge of #137263 - compiler-errors:inherentless, r=lcnr

Register `USAGE_OF_TYPE_IR_INHERENT`, remove inherent usages

I implemented a lint to discourage the usage of `rustc_type_ir::inherent` but never actually enabled it. People started using `rustc_type_ir::inherent` methods through globs, lol.

r? fmease or reassign as you please
