Xianda Ke 9b68645f9e IMPALA-6219: Use AES-GCM for spill-to-disk encryption ...

AES-GCM can be very fast(~10 times faster than CFB+SHA256), but it
requires an instruction that Impala can currently run without (CLMUL).
In order to be fast, we dispatch to GCM mode at run-time based on the
CPU and OpenSSL version.

Testing:
run runtime tmp-file-mgr-test, openssl-util-test, buffer-pool-test
and buffered-tuple-stream-test.
add two cases GcmIntegrity & EncryptoArbitraryLength for
openssl-util-test
