apps/examples/security_test: Add examples of GCM mode

Add UTC and examples of GCM API
Keys should be generated before encryption/decryption.
Factory key is not available in GCM mode.

1) sl_crypto_test
- Example of sl_gcm_encrypt / sl_gcm_decrypt

2) utc_crypto
- UTC of crypto_gcm_encryption / crypto_gcm_decryption
