target/i386: Add feature dependencies for AVX10

Since the highest supported vector length for a processor implies that
all lesser vector lengths are also supported, add the dependencies of
the supported vector lengths. If all vector lengths aren't supported,
clear AVX10 enable bit as well.

Note that the order of AVX10 related dependencies should be kept as:
        CPUID_24_0_EBX_AVX10_128     -> CPUID_24_0_EBX_AVX10_256,
        CPUID_24_0_EBX_AVX10_256     -> CPUID_24_0_EBX_AVX10_512,
        CPUID_24_0_EBX_AVX10_VL_MASK -> CPUID_7_1_EDX_AVX10,
        CPUID_7_1_EDX_AVX10          -> CPUID_24_0_EBX,
so that prevent user from setting weird CPUID combinations, e.g. 256-bits
and 512-bits are supported but 128-bits is not, no vector lengths are
supported but AVX10 enable bit is still set.

Since AVX10_128 will be reserved as 1, adding these dependencies has the
bonus that when user sets -cpu host,-avx10-128, CPUID_7_1_EDX_AVX10 and
CPUID_24_0_EBX will be disabled automatically.
