ANDROID: crypto: testmgr - add back deleted hctr2 test vectors

The merge of 5.15.61 into this branch incorrectly deleted the test
vectors that were added by the following commits:

    commit 00354420 ("UPSTREAM: crypto: xctr - Add XCTR support")
    commit e3efa825 ("UPSTREAM: crypto: polyval - Add POLYVAL support")
    commit d672bb9c ("UPSTREAM: crypto: hctr2 - Add HCTR2 support")

This causes a build error when CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is
not set.  Fix this by adding back the test vectors.
