UefiCpuPkg: Update PT code to support enable collect performance
Update ProcTrace feature code to support enable collect performance
data by generating CYC and TSC packets. Add a new dynamic
PCD to indicate if enable performance collecting. In ProcTrace.c
code, if this new PCD is true, after check cpuid, CYC and TSC
packets will be generated by setting the corresponding MSR bits
feilds if supported.
