HV: Add one correct Descriptor_table struct to configure VMCS

Browse Source 
Now one uint64_t type is used to obtain the corresponding descriptor_table
for GDT/IDT. This will cause the stack protect corruption under -O2.
So the descriptor_table struct is added to configure the GDT/IDT of VMCS.

V1->V2: Move the descriptor_table into vmx.h header file
And its type is renamed from dt_addr_t to descriptor_table.
