qapi: make the vcpu parameters deprecated for 8.1
I don't think I can remove the parameters directly but certainly mark them as deprecated.

The ability to instrument QEMU helper functions with vCPU-aware trace

points was removed in 7.0. However QMP still exposed the vcpu

parameter. This argument has now been deprecated and the remaining

remaining trace points that used it are selected just by name.
