According to UEFI/PI spec, the AllocateXXXPool() interfaces should
return eight-byte aligned buffer that satisfies the required
HEADER_ALIGNMENT which is 4.
This patch adds ASSERT to make sure the bin at required alignment,
that can help catch the issue earlier about incorrect aligned buffer
returned from AllocateXXXPool().
