GIM,IEM: Correctly hook up hypercalls thru IEM. bugref:9044

• IEM: Pass opcode and instruction length to GIM so it can do patching.
• GIM: Introduced GIMHypercallEx API for receiving hypercalls with instruction opcode+length. Hooking this into the exiting #UD code paths.
• GIM: Move the VMMPatchHypercall API into GIM and corrected the name to GIMQueryHypercallOpcodeBytes.
• GIM/KVM: Use GIMQueryHypercallOpcodeBytes to decide which instruction is native and cache the opcode bytes for patching.
• GIM/KVM: Check the VMCALL instruction encoding length rather than assuming its always 3 bytes when patching.
