rustdoc: Missing method signatures in trait docs

[Nemo157]

https://docs.rs/parry2d/0.13.4/parry2d/bounding_volume/trait.BoundingVolume.html

I haven't attempted to really look into what's going wrong, but taking a quick glance at the source and build log on docs.rs there's nothing obviously weird jumping out to me.

Latest version of the crate was built on docs.rs using rustc 1.71.0-nightly (9ecda8de8 2023-04-30) and rustc 1.70.0-nightly (84dd17b56 2023-04-14) and showed the issue, The first version showing the issue was 0.13.1 which was built with rustc 1.69.0-nightly (34e6673a0 2023-02-25) while the last version without the issue was 0.13.0 which was built with rustc 1.68.0-nightly (afaf3e07a 2023-01-14)

@GuillaumeGomez I think you regressed this in #107000.

Specifically, it fails by trying to render a stripped trait item when you re-export a doc(hidden) trait like so:

#[doc(hidden)]
mod hidden {
    pub trait Foo {
        // Hello, world!
        fn test();
    }
}

pub use hidden::Foo;

Specifically, this code does not respect inlining for trait items.

rust/src/librustdoc/passes/strip_hidden.rs

Lines 88 to 96 in 1cb6357

	if !is_hidden && i.inline_stmt_id.is_none() {
	// We don't need to check if it's coming from a reexport since the reexport itself was
	// already checked.
	is_hidden = i
	.item_id
	.as_def_id()
	.and_then(|def_id| def_id.as_local())
	.map(|def_id| inherits_doc_hidden(self.tcx, def_id))
	.unwrap_or(false);

Thanks for the ping @compiler-errors ! I'll fix it in the next hours.
