[crypto/ec] Remove unreachable AVX2 code in NISTZ256 implementation
`crypto/ec/ecp_nistz256.c` contained code sections guarded by a
`ECP_NISTZ256_AVX2` define.
The relevant comment read:
> /*
> * Note that by default ECP_NISTZ256_AVX2 is undefined. While it's great
> * code processing 4 points in parallel, corresponding serial operation
> * is several times slower, because it uses 29x29=58-bit multiplication
> * as opposite to 64x64=128-bit in integer-only scalar case. As result
> * it doesn't provide *significant* performance improvement. Note that
> * just defining ECP_NISTZ256_AVX2 is not sufficient to make it work,
> * you'd need to compile even asm/ecp_nistz256-avx.pl module.
> */
Without diminishing the quality of the original submission, it's evident
that this code has been basically unreachable without modifications to
the library source code and is under-tested.
This commit removes these sections from the codebase.
