Rollup merge of #125452 - Urgau:check-cfg-libraries-cleanup, r=bjorn3
Cleanup check-cfg handling in core and std

Follow-up to https://github.com/rust-lang/rust/pull/125296 where we:
 - expect any feature cfg in std, due to `#[path]` imports
 - move some check-cfg args inside the `build.rs` as per Cargo recommendation
 - and replace the fake Cargo feature `"restricted-std"` by the custom cfg `restricted_std`

Fixes https://github.com/rust-lang/rust/pull/125296#issuecomment-2127009301
