/**
 * The ALIGN_DOWN_POINTER_BY macro aligns a pointer down to a specified alignment boundary.
 *
 * \param Address   The pointer to align.
 * \param Alignment The alignment boundary in bytes (typically a power of two).
 * \return A pointer at or below @p Address aligned down to @p Alignment.
 * \remarks The pointer is treated as an integer (`ULONG_PTR`) for masking.
