In Visual Studio 2022 ARM64EC target the compiler complains about

error C7302: AVX types (__m256) are not currently supported in ARM64EC code
error C7303: AVX512 types (__m512) are not currently supported in ARM64EC code

when I #ifdef everything that looks like avx2/avx512 code, VLOAD() get raw_mults[0] which is null.

So before digging deeper I would like to ask whether any solution already exist to build on ARM64EC.

lib/x86: do not build 256-bit and 512-bit code for Windows ARM64EC

libdeflate failed to build for ARM64EC because it used AVX and AVX512
types which are not supported in ARM64EC code.  Disable these.

Resolves #411
