MmCore ImageSize may be not page aligned, it will be converted to page
aligned for allocating MMRAM to hold MmCore image.
This patch is to call CreatMmHobList() with page aligned size of ImageSize,
otherwise ASSERT (IS_ALIGNED (Length, EFI_PAGE_SIZE)) in
MmIplBuildMmCoreModuleHob() will happen if the input MmCore ImageSize is
not page aligned.
