Jian J Wang adb9f50e4b UefiCpuPkg/UefiCpuPkg.dec: Add two new PCDs for stack switch
Stack switch is required by Stack Guard feature. Following two PCDs are
introduced to simplify the resource allocation for initializing stack switch.

  gUefiCpuPkgTokenSpaceGuid.PcdCpuStackSwitchExceptionList
  gUefiCpuPkgTokenSpaceGuid.PcdCpuKnownGoodStackSize

PcdCpuStackSwitchExceptionList is used to specify which exception will
have separate stack for its handler. For Stack Guard feature, #PF must
be specified at least.

PcdCpuKnownGoodStackSize is used to specify the size of knwon good stack for an
exception handler. Cpu driver or other drivers should use this PCD to reserve
new stack memory for exceptions specified by above PCD.
