+ Provides library services to get and set Platform Configuration Database entries.
+
+ PCD Library Class provides a PCD usage macro interface for all PCD types.
+ It should be included in any module that uses PCD. If a module uses dynamic/dynamicex
+ PCD, module should be linked to a PEIM/DXE library instance to access that PCD.
+ If a module uses PatchableInModule type PCD, it also needs the library instance to produce
+ LibPatchPcdSetPtr() interface. For FeatureFlag/Fixed PCD, the macro interface is
+ translated to a variable or macro that is auto-generated by build tool in
+ module's autogen.h/autogen.c.
+ The PcdGetXX(), PcdSetXX(), PcdToken(), and PcdGetNextTokenSpace() operations are
+ only available prior to ExitBootServices(). If access to PCD values are required
+ at runtime, then their values must be collected prior to ExitBootServices().
+ There are no restrictions on the use of FeaturePcd(), FixedPcdGetXX(),
+ PatchPcdGetXX(), and PatchPcdSetXX().
