[PATCH V7 18/37] OvmfPkg/PlatformInitLib: Add hob functions

["Min Xu" <min.m.xu@intel.com>]

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

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.
