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.

…piler-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.

no-fail-fast support for tool testsuites

~~This commit adds a change to pass "--no-fail-fast" flag to `cargo test` inside `tool::prepare_tool_cargo()` so there is no need to do it manually in each `Step` trait implementation in src/bootstrap/test.rs.~~

~~Also, removes the flag from test.rs where prepare_tool_cargo() is called so cargo doesn't complain because the flag has been passed twice.~~

This commit adds `--no-fail-fast` flag to each `cargo test`
command in each tool Step trait implementation (`miri`, `rustfmt` and `clippy`).
