Motiejus 5682dc0313 build: fix valgrind zig0 tests by disabling all AVX-512 features ...

Valgrind doesn't support AVX-512 instructions (EVEX prefix 0x62).
The zig CC generates them for large struct copies on native x86_64
targets even at -O0 (e.g. vmovdqu64 with zmm registers).

Previously only avx512f was subtracted, which was insufficient —
the .evex512 feature (and other AVX-512 sub-features) also need
to be disabled to prevent EVEX-encoded 512-bit instructions.
