Platform Debug Consent

As a master switch to enable platform debug capability and relevant settings with specified probe type.

Manual: Do not use Platform Debug Consent to override other debug-relevant policies, but the user must set each debug option manually, aimed at advanced users.

|
PDC-dependent policies are listed:
|
DciPreMemConfig->DciEn
|
DciPreMemConfig->DciDbcMode
|
CpuTraceHubConfig->EnableMode
|
CpuTraceHubConfig->CpuTraceHubMemReg0Size

PchTraceHubPreMemConfig->EnableMode
|
PchTraceHubPreMemConfig->MemReg0Size
|
PchTraceHubPreMemConfig->MemReg1Size

Note: DCI OOB (aka BSSB) uses CCA probe.
