Migrate to the 2024 edition (#35755)

* Migrate to 2024 edition

Signed-off-by: Simon Wülker <simon.wuelker@arcor.de>

* Allow unsafe_op_in_unsafe_fn lint

This lint warns by default in the 2024
edition, but is *way* too noisy for servo.

We might enable it in the future, but not now.

* Compile using the 2024 edition
