@W-21933885: [MSDK Android] App Attestation Implementation (Clean Up NativeLoginManager Test Constants And Imports)

- Remove unused mockkStatic import
- Rename URL_UNSAFE_APP_ATTESTATION to UNENCODED_APP_ATTESTATION for clarity
- Remove URL_ENCODED_APP_ATTESTATION constant that is no longer needed
- These changes reflect that attestation values are not URL-encoded in the production code
