Port EdkUnixPkg to UnixPkg. The changes are listed as follows:

1. change *.msa to *.inf, and create platform configuration files .dec&.dsc&.fdf to comply with Edk2 build process
2. using PCD mechanism to replace macro.
3. change Sec code to cowork with PI1.0 Pei Core and produce temparory memory ppi.

+  IN UINT32                       TickNumber

+  )

+/*++

+

+Routine Description:

+

+  The WaitForTick() function waits for the number of ticks specified by

+  TickNumber from a known time source in the platform.  If TickNumber of

+  ticks are detected, then EFI_SUCCESS is returned.  The actual time passed

+  between entry of this function and the first tick is between 0 and

+  TickPeriod 100 nS units.  If you want to guarantee that at least TickPeriod

+  time has elapsed, wait for two ticks.  This function waits for a hardware

+  event to determine when a tick occurs.  It is possible for interrupt

+  processing, or exception processing to interrupt the execution of the

+  WaitForTick() function.  Depending on the hardware source for the ticks, it

+  is possible for a tick to be missed.  This function cannot guarantee that

+  ticks will not be missed.  If a timeout occurs waiting for the specified

+  number of ticks, then EFI_TIMEOUT is returned.

+

+Arguments:

+

+  This       - The EFI_METRONOME_ARCH_PROTOCOL instance.

+  TickNumber - Number of ticks to wait.

+

+Returns:

+

+  EFI_SUCCESS - The wait for the number of ticks specified by TickNumber

+                succeeded.
