crypto/aes: On ppc64le, use better instructions when available
Several operations emulate instructions available on power9. Use
the GOPPC64_power9 macro provided by the compiler to select the
native instructions if the minimum cpu requirements are met.
Likewise rework the LXSDX_BE to simplify usage when overriding
it. It is only used in one place.
All three configurations are tested via CI.
On POWER9:
pkg:crypto/cipher goos:linux goarch:ppc64le
AESCBCEncrypt1K 949MB/s ± 0% 957MB/s ± 0% +0.83%
AESCBCDecrypt1K 1.82GB/s ± 0% 1.99GB/s ± 0% +8.93%
pkg:crypto/aes goos:linux goarch:ppc64le
Encrypt 1.01GB/s ± 0% 1.05GB/s ± 0% +4.36%
Decrypt 987MB/s ± 0% 1024MB/s ± 0% +3.77%
