This branch updates our Rust toolchain to nightly-2024-01-20. To build
on this nightly, I've removed a no-longer-necessary feature flag, and
updated our mycelium deps to
hawkw/mycelium@1de8ba1, which includes
fixes for a bunch of new warnings added on recent Rust toolchains.

this PR changes the toolchain to use `nightly-2024-07-30` and fixes
`platforms/x86_64` dependencies so it uses root's `Cargo.toml` patch
section for maitake crates.


closes #323 

obsoletes #306

TODO for reviewers (roughly ordered by assumed importance):
- [ ] ensure `target_has_atomic` is the right fix (
a9e59b1 )
- [ ] [warning: transmute used without annotations -->
platforms/allwinner-d1/d1-core/src/drivers/smhc.rs:521:58](https://github.com/tosc-rs/mnemos/blob/update-toolchain/platforms/allwinner-d1/d1-core/src/drivers/smhc.rs#L521)
- [ ] [interior mutable const
lint](https://github.com/tosc-rs/mnemos/blob/80928e4f13d97ac4e21655ff19b82fa0e5fc2e43/source/spitebuf/src/lib.rs#L182)
- [ ] `VAddr::of(&DOUBLE_FAULT_STACK)` ( 1aecece ) - can't use clippy's
suggested `ptr::addr_of!` with pinned mycelium (probably best to create
dedicated issue)
- [ ] warning: struct `GrantWriter` is never constructed:
