Don't specify proc-macro-test version
proc-macro-test is only used as a dev-dependency and isn't published to crates.io, so a version doesn't make sense. Having a version also breaks automatic publishing.

Use anonymous lifetime where possible
Because anonymous lifetimes are *super* cool.
More seriously, I believe anonymous lifetimes, especially those in impl headers, reduce cognitive load to a certain extent because they usually signify that they are not relevant in the signature of the methods within (or that we can apply the usual lifetime elision rules even if they are relevant).
Fix runnable detection for `#[tokio::test]`
fix#15141
It is hacky, and it wouldn't work for e.g. this case:
```Rust
use ::core::prelude;
#[prelude::v1::test]
fn foo() {
}
```
But it works for the tokio case. We should use the name resolution here somehow, and after that we should probably also get rid of the ast based `test_related_attribute` function.
internal: add `library` fixture meta
Currently, there is no way to specify `CrateOrigin` of a file fixture ([this] might be a bug?). This PR adds `library` meta to explicitly specify the fixture to be `CrateOrigin::Library` and also makes sure crates that belong to a library source root are set `CrateOrigin::Library`.
(`library` isn't really the best name. It essentially means that the crate is outside workspace but `non_workspace_member` feels a bit too long. Suggestions for the better name would be appreciated)
Additionally:
- documents the fixture meta syntax as thoroughly as possible
- refactors relevant code

Fix `self` and `super` path resolution in block modules
This PR fixes `self` and `super` path resolution with block modules involved.
Previously, we were just going up the module tree count-of-`super` times without considering block modules in the way, and then if we ended up in a block `DefMap`, we adjust "to the containing crate-rooted module". While this seems to work in most real-world cases, we failed to resolve them within peculiar module structures.
`self` and `super` should actually be resolved to the nearest non-block module, and the paths don't necessarily resolve to a crate-rooted module. This PR makes sure every `self` and `super` segment in paths are resolved to a non-block module.
internal: support `#[rustc_coinductive]`
rust-lang/rust#100386 changed the trait solver so that `Sized` is treated as coinductive trait, just like auto traits. This is now controlled by the perma-unstable `#[rustc_coinductive]` attribute (rust-lang/rust#108033), which this PR adds support for.
In practice, I don't think this matters much if at all. Currently we don't give chalk enough information so chalk cannot precisely (dis)prove `Sized` bounds.
