Auto merge of #82565 - m-ou-se:ununstabilize-bits, r=kennytm

Revert reverting of stabilizing integer::BITS. Now that `lexical-core` has an updated version that won't break with this stabilization, let's try to stabilize this again. See #81654 (comment) Tracking issue with FCP: #76904

 // Technically, this is a bug in rustdoc: rustdoc sees the documentation on `#[lang = slice_alloc]`
 // blocks is for `&[T]`, which also has documentation using this feature in `core`, and gets mad
 // that the feature-gate isn't enabled. Ideally, it wouldn't check for the feature gate for docs
