OvmfPkg/PlatformPei: Refactor AddressWidthInitialization

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3863

From this patch we start to restruct the functions which set PCDs into
two, one for PlatformInitLib, one for PlatformPei.

AddressWidthInitialization is the first one. It is splitted into two:
 - PlatformAddressWidthInitialization is for PlatformInitLib
 - AddressWidthInitialization is for PlatformPei. It calls
   PlatformAddressWidthInitialization then set PCDs.

Below functions are also refined for PlatformInitLib:
 - PlatformScanOrAdd64BitE820Ram
 - PlatformGetSystemMemorySizeAbove4gb
 - PlatformGetFirstNonAddress

All the SetPcd codes are removed from above functions.
