…heemdev std: move `kernel_copy` to `sys` Part of rust-lang#117276. The current organisation of the `kernel_copy` mechanism used to specialise `io::copy` on Linux necessitated circular links between the `io::copy` module and the implementation in `sys::pal::unix::kernel_copy`, as well as presenting an exception to the tidy PAL rule that forbids OS-based `#[cfg]`s outside of `sys` and `os`. This PR fixes this by moving `kernel_copy` to `sys` (as per rust-lang#117276) and returning a `CopyState` from that function specifying whether `io::copy` should use its fallback. The `kernel_copy` function on other platforms just unconditionally returns `CopyState::Fallback`.

…nts, r=RalfJung doc: fix `strict_provenance_lints` tracking issue link This PR is a follow-up on rust-lang@56ee492 and fixes the link to the `strict_provenance_lints` tracking issue. I am not sure whether we should touch this line too: https://github.com/rust-lang/rust/blob/66bc5a43e55eae14a2ec70b11004c88072fe7f02/compiler/rustc_lint_defs/src/builtin.rs#L2537 r? `@RalfJung`

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
