Update rust toolchain to 1.84 (#3945)

* chore: Remove deprecated `Makefile.toml`

which really should have been deleted as part of #2012. This hasn't been
updated for more than 2 years now and I don't expect anyone to still use
this. Our build process is now managed by `cargo xtask`.

* Cargo: Update the Rust toolchain to 1.84.0

from 1.75.0 which has been deprecated for a while now. Along with this
change, the `wasm32-wasi` target is no longer available (see subsequent
commit for additional info).

* chore: Rename `wasm32-wasi` to `wasm32-wasip1`

as required by the Rust project. The `wasm32-wasi` target name has been
retired and will likely be reused at a later time, although to express
an entirely different target (i.e. implementation of the WASI standard).

For additional information, see:

  - https://blog.rust-lang.org/2024/04/09/updates-to-rusts-wasi-targets.html
  - https://blog.rust-lang.org/2024/09/05/Rust-1.81.0.html#wasi-01-target-naming-changed

* chore: Drop `rust-analysis` component

from the `rust-toolchain.toml` definition. This was added way back in
2021 via 8688569a, and while I'm not sure what it expressed back then,
nowadays it refers to [Metadata for RLS][1], which apparently was an
early language server implementation and has long since been replaced by
*rust-analyzer*.

We don't want to propose or enforce the use of a specific toolchain and
in any case, setting this up properly is the job of a developers
IDE/Editor.

* chore: Adhere to type rename

from `std::panic::PanicInfo` to `std::panic::PanicHookInfo`, which was
introduced in Rust 1.81.0. For additional information, see:

- https://releases.rs/docs/1.81.0/#compatibility-notes
- https://github.com/rust-lang/rust/pull/115974/

* fix(utils/data): Adhere to expected case

in match arm patterns, since the expression being matched against has
been modified using `to_ascii_lowercase`. Hence, we cannot have upper
case ASCII chars in the expressions (these arms were previously no-ops).

* fix(utils): Derive `Hash` manually

in `input/layout` since the `PartialEq` trait is also implemented
manually. Previously the `Hash` impl wasn't consistent with the `Eq`
impl, which can have weird effects when using these types in e.g.
`HashMap`s or similar types. For additional information, see:

  - https://rust-lang.github.io/rust-clippy/master/index.html#derived_hash_with_manual_eq
  - https://doc.rust-lang.org/stable/std/hash/trait.Hash.html#hash-and-eq

* fix(utils): Derive `Hash` manually

in `pane_size` since the `PartialEq` trait is also implemented manually.
Previously the `Hash` impl wasn't consistent with the `Eq` impl, which
can have weird effects when using these types in e.g. `HashMap`s or
similar types. For additional information, see:

  - https://rust-lang.github.io/rust-clippy/master/index.html#derived_hash_with_manual_eq
  - https://doc.rust-lang.org/stable/std/hash/trait.Hash.html#hash-and-eq

* fix(server): Don't redeclare variables

with their same names. Latest rust toolchains reject this code.

* chore(actions): Use non-archived toolchain setup

for the Rust toolchain. The previously used action has been archived
over a year ago. The new one should also support reading our
`rust-toolchain.toml`, so we no longer have to keep track of the
toolchain in multiple places.

* chore(actions): Add some space to YAML files

to make them better visually parsable.

* ci: Remove toolchain update Job

since as far as I can tell, this isn't used any more.

* ci: Fix invalid actions specification

and only request an action without running other code.

* CHANGELOG: Add PR #3945.
