[X86][AVX10] Disable m[no-]avx10.1 and switch m[no-]avx10.2 to alias of 512
Per the feedback we got, we’d like to switch m[no-]avx10.2 to alias of 512 bit options and disable m[no-]avx10.1 due to they were alias of 256 bit options. We also change -mno-avx10.[1,2]-512 to alias of 256 bit options to disable both 256 and 512 instructions.
