Add an AES-XTS implementation "xts-aes-vaes-avx10_512" for x86_64 CPUs
with the VAES, VPCLMULQDQ, and either AVX10/512 or AVX512BW + AVX512VL
extensions.  This implementation uses zmm registers to operate on four
AES blocks at a time.  The assembly code is instantiated using a macro
so that most of the source code is shared with other implementations.

To avoid downclocking on older Intel CPU models, an exclusion list is
used to prevent this 512-bit implementation from being used by default
on some CPU models.  They will use xts-aes-vaes-avx10_256 instead.  For
now, this exclusion list is simply coded into aesni-intel_glue.c.  It
may make sense to eventually move it into a more central location.

xts-aes-vaes-avx10_512 is slightly faster than xts-aes-vaes-avx10_256 on
some current CPUs.  E.g., on AMD Zen 4, AES-256-XTS decryption
throughput increases by 13% with 4096-byte inputs, or 14% with 512-byte
inputs.  On Intel Sapphire Rapids, AES-256-XTS decryption throughput
increases by 2% with 4096-byte inputs, or 3% with 512-byte inputs.

Future CPUs may provide stronger 512-bit support, in which case a larger
benefit should be seen.
