chore: make credential dependencies platform-specific

### What does this PR try to resolve?

Starting from #11993, we made `cargo-credential-macos-keychain` and `cargo-credential-wincred` able to build on all platforms. However, some of their dependencies are not. This PR turns them into platform specific dependencies to circumvent the situation.

### How should we test and review this PR?

Run the following commands on all platforms Cargo supports.

```
cargo check --workspace --exclude cargo-credential-gnome-secret
```
