 * The PF_PHYSICAL_MEMORY_RANGE_INFO_V2 structure receives physical-memory ranges from SuperfetchMemoryRangesQuery.

 * 16 bytes, each range is 16 bytes, and the buffer requires 8-byte alignment. Required capacity is
 * 16 + 16 * RangeCount bytes and is returned through query ReturnLength on STATUS_BUFFER_TOO_SMALL.
 * RangeCount is written only when the buffer is large enough. BasePfn and PageCount are in 4096-byte page units.
