[stable] Prepare Rust 1.75.0 release

This PR includes the squash of the release notes from https://github.com/rust-lang/rust/pull/118729, and bumps the channel to stable to prepare release artifacts.

The only `beta-nominated` PR is https://github.com/rust-lang/rust/pull/118796, which is still waiting for review and is not `beta-accepted` yet, so this does **not** backport it. `@Nadrieril` `@cjgillot` `@apiraino` if that PR becomes ready to be backported before the 28th ping me on Zulip and I can rebuild artifacts with it.

r? `@ghost`
