Update Rust Nightly Oct 2024

Pull Request Overview

Update to a new nightly.

The changes to use Self are to fix warnings like these:

warning: elided lifetime has a name
  --> capsules/extra/src/ambient_light.rs:57:10
   |
53 | impl<'a> AmbientLight<'a> {
   |      -- lifetime `'a` declared here
...
57 |     ) -> AmbientLight {
   |          ^^^^^^^^^^^^ this elided lifetime gets resolved as `'a`

Testing Strategy

TODO or Help Wanted

This adds a bunch of warnings like:

warning: `raspberry_pi_pico` (bin "raspberry_pi_pico") generated 1 warning
warning: creating a shared reference to mutable static is discouraged
   --> chips/sam4l/src/dma.rs:223:17
    |
223 |                 NUM_ENABLED.fetch_add(1, atomic::Ordering::Relaxed);
    |                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ shared reference to mutable static
    |
    = note: for more information, see <https://doc.rust-lang.org/nightly/edition-guide/rust-2024/static-mut-references.html>
    = note: shared references to mutable statics are dangerous; it's undefined behavior if the static is mutated or if a mutable reference is created for it while the shared reference lives
    = note: `#[warn(static_mut_refs)]` on by default

so...we need to do something about that.

Documentation Updated

• Updated the relevant files in /docs, or no updates are required.

Ran the update script.

Formatting

• Ran make prepush.

Huh. I guess if this is no longer unsafe, then the comment above should have the "SAFETY:" removed. The reset of the commend can probably stay, but let's not signal it as an unsafe block if it's not.

Shouldn't merge this until we deal with the warnings.
