Aorimn fb67fae83a Add AES-XEX tests cases
The test cases come from the XTS test vectors given by the CAVP initiative
from NIST (see [1]).
As mentioned in a previous commit, XEX is a simpler case of XTS.
Therefore, to construct the test_suite_aes.xex.data file, extraction of
the XEX-possible cases has been done on the given test vectors.
All of the extracted test vectors pass the tests on a Linux x86_64 machine.
