fix: Add missing cfg flags for `core` crate

Some types in `core` are conditionally compiled based on
`target_has_atomic` or `target_has_atomic_load_store` without an
argument, for example `AtomicU64`.

This is less noticeable in Cargo projects, where rust-analyzer adds
the output `RUSTC_BOOTSTRAP=1 cargo rustc --print cfg` so it gets the
full set of cfg flags.

This fixes go-to-definition on `std::sync::atomic::AtomicU64` in
non-cargo projects.
