Add ARMv8-CE HW acceleration for GCM-SIV counter mode
* cipher/rijndael-armv8-aarch32-ce.S
(_gcry_aes_ctr32le_enc_armv8_ce): New.
* cipher/rijndael-armv8-aarch64-ce.S
(_gcry_aes_ctr32le_enc_armv8_ce): New.
* cipher/rijndael-armv8-ce.c
(_gcry_aes_ctr32le_enc_armv8_ce)
(_gcry_aes_armv8_ce_ctr32le_enc): New.
* cipher/rijndael.c
(_gcry_aes_armv8_ce_ctr32le_enc): New prototype.
(do_setkey): Add setup of 'bulk_ops->ctr32le_enc' for ARMv8-CE.

Benchmark on Cortex-A53 (aarch64):
Before:
AES | nanosecs/byte mebibytes/sec cycles/byte auto Mhz
GCM-SIV enc | 11.77 ns/B 81.03 MiB/s 7.63 c/B 647.9
GCM-SIV dec | 11.92 ns/B 79.98 MiB/s 7.73 c/B 647.9
GCM-SIV auth | 2.99 ns/B 318.9 MiB/s 1.94 c/B 648.0
After (~2.4x faster):
AES | nanosecs/byte mebibytes/sec cycles/byte auto Mhz
GCM-SIV enc | 4.66 ns/B 204.5 MiB/s 3.02 c/B 647.9
GCM-SIV dec | 4.82 ns/B 198.0 MiB/s 3.12 c/B 647.9
