xtest: pkcs11_1030: Test AES GCM processing

Add pkcs11_1030 test case for CKM_AES_GCM encryption and decryption tests
based on AES GCM test vectors from regression_4000_data.h.

Each vector is tested with both the one-shot API function C_Encrypt()
(resp. C_Decrypt()) and the update/final stepped processing API functions
C_EncryptUpdate() and C_EncryptFinal() (resp. C_DecryptUpdate() and
C_DecryptFinal()). Each test vector is also tested with modified cipher
text and modified authentication for a negative case.
