Fix asym tests to return TEST_SKIPPED when session
creation returns -ENOTSUP. Add missing ECDH, ECDSA and ECPM
capabilities to GEN4 asym caps table. Reject unsupported RSA
padding and EC curves at session configure time with -ENOTSUP.

QAT HW rounds the output buffer size up to the next supported size,
but result.length was set to alg_bytesize instead of n.length, causing
result comparisons to read past the end of the expected value.
Additionally, when a modulus has a leading zero padding byte, QAT HW
strips it from the result but we never strip it from the expected result,
so the compare fails. Fix verify_modexp() and verify_modinv() to skip
leading zero bytes in the result before comparison.

Fix asym tests to return TEST_SKIPPED when session creation returns -ENOTSUP. Add missing ECDH, ECDSA and ECPM capabilities to GEN4 asym caps table. Reject unsupported RSA padding and EC curves at session configure time with -ENOTSUP. Bugzilla

Fix asym tests to return TEST_SKIPPED when session
creation returns -ENOTSUP. Add missing ECDH, ECDSA and ECPM
capabilities to GEN4 asym caps table. Reject unsupported RSA
padding and EC curves at session configure time with -ENOTSUP.
