[PATCH v2 0/4] Enable Rust by default

["brian m. carlson" <sandals@crustytoothpaste.net>]

Our breaking changes document said that we would enable Rust support by
default in Git 2.53, while still leaving the ability for it to be
disabled.  Unfortunately, we forgot to do that and my time machine is
broken right now, so this series sets it up for Git 2.54.

CI remains passing on GitHub Actions in v2.

Changes since v1:

* Move Cargo declaration to src/meson.rs.
* Add a Meson build without Rust.
* Remove `-Drust=enabled` for Meson, which is no longer needed.
