target/i386/cpu: Add dependencies of CPUID 0x12 leaves

Browse Source 
As SDM stated, CPUID 0x12 leaves depend on CPUID_7_0_EBX_SGX (SGX
feature word).

Since FEAT_SGX_12_0_EAX, FEAT_SGX_12_0_EBX and FEAT_SGX_12_1_EAX define
multiple feature words, add the dependencies of those registers to
report the warning to user if SGX is absent.
