Add check for invalid #[macro_export] arguments

Resolves rust-lang#107231
Sorry if I made something wrong, this is my first contribution to the repo.

Move some `InferCtxt` methods to `EvalCtxt` in new solver

Moving towards eventually making the `InferCtxt` within `EvalCtxt` private, so that we make sure not to do anything strange in the solver. This doesn't finish this work yet, just gets it started.

Don't delay `ReError` bug during lexical region resolve

Lexical region resolution returns a list of `RegionResolutionError` which don't necessarily correspond to diagnostics being emitted. The compiler may, validly, throw away these resolution errors and do something else. Therefore it's not valid to use `ReError` during lifetime resolution, since we may actually be on a totally fine compilation path.

For example, the `implied_bounds_entailment` lint runs region resolution twice, and only emits an error if it fails both times. If we delay a bug and create a `ReError` during this first run, then we will ICE.

Fixes rust-lang#108170

----

Side-note: this is conceptually equivalent to how we can't necessarily delay bugs or create `ty::Error` during trait solving/fulfillment, since the compiler is allowed to throw away these fulfillment errors to do other things. It's only once we actually emit an error (`report_region_errors` / `report_fulfillment_errors`)

Fix overlapping spans in removing extra arguments

Fixes rust-lang#108225

Each span is already extended to include the previous comma, so extending to the *next* comma is unecessary and causes an ICE with assertions on.
