OvmfPkg/PlatformInitLib: Add hob functions

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3863 In this patch of PlatformInitLib, below hob functions are introduced: - PlatformAddIoMemoryBaseSizeHob - PlatformAddIoMemoryRangeHob - PlatformAddMemoryBaseSizeHob - PlatformAddMemoryRangeHob - PlatformAddReservedMemoryBaseSizeHob They correspond the below functions in OvmfPkg/PlatformPei: - AddIoMemoryBaseSizeHob - AddIoMemoryRangeHob - AddMemoryBaseSizeHob - AddMemoryRangeHob - AddReservedMemoryBaseSizeHob After above hob functions are introduced in PlatformInitLib, OvmfPkg/PlatformPei is refactored with this library.
