Stablize {HashMap,BTreeMap}::into_{keys,values}

I would propose to stabilize `{HashMap,BTreeMap}::into_{keys,values}`( aka. `map_into_keys_values`).

Closes rust-lang#75294.

Simplify chdir implementation and minimize unsafe block

Allow using `core::` in intra-doc links within core itself

I came up with this idea ages ago, but rustdoc used to ICE on it. Now it doesn't.

Helps with rust-lang#73445. Doesn't fix it completely since `extern crate self as std;` in std still gives strange errors.

Handle incorrect placement of parentheses in trait bounds more gracefully

Fix rust-lang#84772.

CTFE engine: rename copy → copy_intrinsic, move to intrinsics.rs

The `copy` name is confusing for this function because we also have `copy_op` which is pretty different. I hope `copy_intrinsic` is clearer. Also `step.rs` should really just contain the main loop and opcode dispatch, so move this helper function to a more appropriate place.
