TscTimerLib in PerformancePkg is a BASE type library, which should be used by any module type.

But its constructor uses the global variable mTscFrequency to store frequency, which doesn't work on XIP PEIM.
Split it to two LIBs for PEI and DXE separately.

+#  Pei Timer Library which uses the Time Stamp Counter in the processor.
+#
+#  A version of the Timer Library using the processor's TSC.
+#  The time stamp counter in newer processors may support an enhancement, referred to as invariant TSC.
+#  The invariant TSC runs at a constant rate in all ACPI P-, C-. and T-states.
+#  This is the architectural behavior moving forward.
+#  TSC reads are much more efficient and do not incur the overhead associated with a ring transition or
+#  access to a platform resource.
