Rollup merge of #125597 - compiler-errors:early-binder, r=jackh726

Browse source 
Uplift `EarlyBinder` into `rustc_type_ir`

We also need to give `EarlyBinder` a `'tcx` param, so that we can carry the `Interner` in the `EarlyBinder` too. This is necessary because otherwise we have an unconstrained `I: Interner` parameter in many of the `EarlyBinder`'s inherent impls.

I also generally think that this is desirable to have, in case we later want to track some state in the `EarlyBinder`.
