UefiCpuPkg/PiSmmCpuDxeSmm: Enable single step after SmmProfile start
There is a bug in the existing code: the single step is always enabled
once the Page Fault (#PF) occurs, but it is only disabled when the SMM
Profile feature actually starts (see DebugExceptionHandler).
If the SMM Profile feature has not been started, this will result in
the single-step mode remaining enabled if a Page Fault occurs.
This patch is to enable the single-step debugging mode by setting the
Trap Flag only after SmmProfile feature starts.
