library: fix some stability annotations This PR updates some stability attributes to correctly reflect when some items actually got stabilized. Found while testing rust-lang#132481. ### `core::char` / `std::char` In rust-lang#26192, the `core::char` module got "stabilized" for 1.2.0, but the `core` crate itself was still unstable until 1.6.0. In rust-lang#49698, the `std::char` module was changed to a re-export of `core::char`, making `std::char` appear as "stable since 1.2.0", even though it was already stable in 1.0.0. By marking `core::char` as stable since 1.0.0, the docs will show correct versions for both `core::char` (since 1.6.0) and `std::char` (since 1.0.0). This is also consistent with the stabilities of similar re-exported modules like `core::mem`/`std::mem` for example. ### `{core,std}::array` and `{core,std}::array::TryFromSliceError` In rust-lang#58302, the `core::array::TryFromSliceError` type got stabilized for 1.34.0, together with `TryFrom`. At that point the `core::array` module was still unstable and a `std::array` re-export didn't exist, but `core::array::TryFromSliceError` could still be named due to rust-lang#95956 to existing yet. Then, `core::array` got stabilized and `std::array` got added, first targeting 1.36.0 in rust-lang#60657, but then getting backported for 1.35.0 in rust-lang#60838. This means that `core::array` and `std::array` actually got stabilized in 1.35.0 and `core::array::TryFromSliceError` was accessible through the unstable module in 1.34.0 -- mark them as such so that the docs display the correct versions.

Rollup merge of rust-lang#132481 - lukas-code:doc-stab3, r=GuillaumeGomez rustdoc: skip stability inheritance for some item kinds For some item kinds it's incorrect to inherit their parent's stability, because they might be accessible without referring to the parent directly -- This PR removes the stability inheritance for these items and reverts their displayed stability to that before rust-lang#130798. Impl items, both inherent and trait impls, have a stability, but it is ignored when checking for enabled features. However, impl items are automatically unstable if they're nested inside an unstable module -- this caused the children of impl to inherit the instability and lead to rust-lang#132440. Furthermore, for associated items only the stability of the associated item itself is checked and not that of its parent impl. This is true even for trait impls and we have [relied on this behavior in the standard library in the past](https://doc.rust-lang.org/1.37.0/std/slice/trait.SliceConcatExt.html#tymethod.concat), so these also shouldn't inherit the impl's stability. I've also removed the stability inheritance for primitives and keywords so that viewing e.g. [the `i32` docs on `core`](https://doc.rust-lang.org/nightly/core/primitive.i32.html) will no longer show "since 1.6.0". Note that we currently don't annotate stability for the keyword docs, but if we start doing so in the future then this is probably more correct. fixes (after backport) rust-lang#132440

For some item kinds it's incorrect to inherit their parent's stability, because they might be accessible without referring to the parent directly -- This PR removes the stability inheritance for these items and reverts their displayed stability to that before #130798.
Impl items, both inherent and trait impls, have a stability, but it is ignored when checking for enabled features. However, impl items are automatically unstable if they're nested inside an unstable module -- this caused the children of impl to inherit the instability and lead to #132440.
Furthermore, for associated items only the stability of the associated item itself is checked and not that of its parent impl. This is true even for trait impls and we have relied on this behavior in the standard library in the past, so these also shouldn't inherit the impl's stability.
I've also removed the stability inheritance for primitives and keywords so that viewing e.g. the
i32docs oncorewill no longer show "since 1.6.0". Note that we currently don't annotate stability for the keyword docs, but if we start doing so in the future then this is probably more correct.fixes (after backport) #132440
