Add a new Timer Library instance SecPeiDxeTimerLibUefiCpu into UefiCpuPkg. This library differs with the SecPeiDxeTimerLibCpu library in the MdePkg in that it uses the local APIC library so that it supports x2APIC mode.

+# Instance of Timer Library only using CPU resources.
+#
+# Timer Library that only uses CPU resources to provide calibrated delays
+#  on IA-32, x64, and IPF.
+# Note: Because CPU Local APIC and ITC could be programmed by OS, it cannot be
+#  used by SMM drivers and runtime drivers, ACPI timer is recommended for SMM
+#  drivers and runtime drivers.
