[PRQ#52328] Deletion Request for meson-rust Rejected

Request #52328 has been Rejected by MarsSeed [1]: Package has been updated. And now it includes relevant patches from an experimental pull request (PR#12536), which aims to bring improvements for certain Rust compilation scenarios. Therefore this PKGBUILD is a legitimate addition to the AUR. [1] https://aur.archlinux.org/account/MarsSeed/
