chore: update rust edition to 2024

[nakajimayoshi]

This change updates the crate to be compatible with the latest edition of rust (2024 as of creating this). without introducing any breaking API changes.

I have squashed some of the existing compiler errors but the vast majority seem to be stemming from a bindgen rust file that's generated at compile time.

Edit: I managed to get rid of the build errors by updating bindgen to the latest version

LGTM

Some additional changes to get clippy to work:

Disable layout tests in Bindgen

The MSFS SDK headers use interfaces with virtual methods. You can't really perform meaningful layout tests when you're interacting with these types via opaque pointers instead of passing by value.

#![allow(unsafe_op_in_unsafe_fn)]

Adding unsafe blocks to the bodies of all the unsafe functions would involve adding more boilerplate to the build.rs file than is needed, for no additional safety benefit. The functions themselves are already marked as unsafe.
