Remove `intercrate` and `mark_ambiguous` from `TypeRelation`
Fixes#109863
Pulls this logic into `super_combine_tys`, which has access to `InferCtxt` and takes a `ObligationEmittingRelation` -- both of which simplify the logic here.

Add `tests_outside_test_module` lint
Adds `tests_outside_test_module` from #10506. This PR **doesn't** close the issue, just resolves task 1.
changelog: [`tests_outside_test_module`]: The lint has been added
Previously if the expression contained generic consts and did not have a directly equivalent
type, transmuting the type in this way was forbidden, despite the two sizes being identical.
Instead, we should be able to lazily tell if the two consts are identical, and if so allow them
to be transmuted.
Fix bug with getting parent directories in `lookup_conf_file`
Currently `lookup_conf_file` doesn't canonicalize the configuration directory before using [`PathBuf::pop`](https://doc.rust-lang.org/std/path/struct.PathBuf.html#method.pop) to get the parent directory. This isn't usually an issue when clippy is invoked via `cargo clippy` as `CARGO_MANIFEST_DIR` is already canonicalized. However, this currently causes `clippy-driver` to ignore any `clippy.toml` in any parent directories when `CARGO_MANIFEST_DIR` and `CLIPPY_CONF_DIR` are not set.
changelog: Fix a bug that would cause parent directories not to be searched for `clippy.toml` when using `clippy-driver` directly.
Remove optimal xz settings from CI
This is a companion PR to rust-lang/promote-release#58, which moves the relevant optimal code to rust-lang/promote-release. As mentioned in the comments of that PR, this is expected to cut CI costs (and time, though predominantly felt on fast builders) and reduce wasted resources due to in-practice single-threaded compression not using the full 8+ vCPU builders we have available.
This probably shouldn't land before that PR + a simpleinfra change to enable the recompression of xz artifacts. But if it does land, it's just a matter of a few nightlies with slightly larger artifacts, so not a big deal.
