Sometimes a platform knows exactly how many CPUs it has at boot. It should be able to - set PcdCpuMaxLogicalProcessorNumber dynamically to this number, - set PcdCpuApInitTimeOutInMicroSeconds to a very long time (for example MAX_UINT32, approx. 71 minutes), - and expect that MpInitLib wait exactly as long as necessary for all APs to report in. Other platforms should be able to continue setting a reasonably large upper bound on supported CPUs, and waiting for a reasonable, fixed amount of time for all APs to report in. Add this functionality. The TimedWaitForApFinish() function will return when all APs have reported in, or the timeout has expired -- whichever happens first. (Accessing these PCDs dynamically is safe. The PEI and DXE phase instances of this library are restricted to PEIM and DXE_DRIVER client modules, thus the PCD accesses cannot be linked into runtime code.)
