settings: Remove @hide NFC API usage

These @hide usages in other parts of platform need to be cleaned
up to unbundle NFC mainline module.

Flag: None (The NFC flag - `enableNfcMainline` has been promoted to trunkfood. Note these APIs are available as @hide even if not available in formal SDK until V)
Bug: 307352220
Test: Compiles
