[X86][AVX10] Permit AVX512 options/features used together with AVX10 (#71318)
This patch relaxes the driver logic to permit combinations between AVX512 and AVX10 options and makes sure we have a unified behavior between options and features combination. Here are rules we are following when handle these combinations: 1. evex512 can only be used for avx512xxx options/features. It will be ignored if used without them; 2. avx512xxx and avx10.xxx are options in two worlds. Avoid to use them together in any case. It will enable a common super set when they are used together. E.g., "-mavx512f -mavx10.1-256" euqals "-mavx10.1-512". Compiler emits warnings when user using combinations like "-mavx512f -mavx10.1-256" in case they won't get unexpected result silently. Function target feature attribute follows the same rule now. We have to add "no-evex512" feature for intrinsics shared between AVX512 and AVX10. We also add "no-evex512" for early ISAs like AVX etc., because some of them are called by AVX512 intrinsics.
