KVM: SVM: Create trace events for VMGEXIT MSR protocol processing
Add trace events for entry to and exit from VMGEXIT MSR protocol processing. The vCPU will be common for the trace events. The MSR protocol processing is guided by the GHCB GPA in the VMCB, so the GHCB GPA will represent the input and output values for the entry and exit events, respectively. Additionally, the exit event will contain the return code for the event.
