Summary

Notably, define AES_ASM which is required for any AES acceleration
(OpenSSL 1.0 gated all AES acceleration on OPENSSL_CPUID_OBJ instead).
Enabling this exposed that new files assembly files added in OpenSSL 3.0
needed to be included in the build (aes-x86-64.S and aes-586.S). Both
of files supplant both aes_core.c and aes_cbc.c. The last file now had
to be moved out of the MI SRCS line for aes and into each ASM_* for
non-x86.

As part of this I audited the generated configdata.pm for amd64, i386,
and aarch64 and found the following additional discrepecancies that are
fixed here as well:

  • Enabled BSAES_ASM on amd64 which requires bsase-x86_64.S
  • Enabled WHIRLPOOL_ASM on amd64 (asm sources already built)
  • Enabled CMLL_ASM on amd64 and i386 (asm sources already built)

aarch64 had no discreprecancies in configdata.pm, and no *.pl asm
generators were missing for aarch64 in Makefile.asm. I did not check
powerpc or armv7, but for armv7 all of the asm generators seem to be
present in Makefile.asm.

On my desktop this change mostly restores the performance of AES-128-GCM measured by openssl speed.

Current main in a VM:

type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes  16384 bytes

After installing updated libcrypto.so in VM:

type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes  16384 bytes

From stable/13 OpenSSL 1.1.x on the host:
