target/i386/cpu: Fix CPUID_HT exposure
When explicitly booting a multiple vcpus vm with "-cpu +ht", it gets
warning of
warning: host doesn't support requested feature: CPUID.01H:EDX.ht [bit 28]
Make CPUID_HT as supported unconditionally can resolve the warning.
However it introduces another issue that it also expose CPUID_HT to
guest when "-cpu host/max" with only 1 vcpu. To fix this, need mark
CPUID_HT as the no_autoenable_flags.
