Subject: [PATCH] chore(deps): Depend on `serde_core` in `cargo-platform`

`cargo-platform` does not make use of serde derive macros, thus it can
depend on `serde_core` instead of `serde` to speed up users' compile
times.

See the documentation of [`serde_core`](https://docs.rs/serde_core)
for more details.
