> [Format] Clarify language around buffer padding and alignment in IPC

> We recommend 64-byte padding in memory allocations, but in practice some
> systems may emit buffers that are only 8-byte aligned. We should take a look
> through the format documents and perhaps indicate that 64-byte padding is the
> _preferred_ padding but that 8-byte padding is the _required_ padding.
> In particular, it should be clear that each buffer in an IPC payload must
> start on an aligned 8-byte offset, but it does not necessarily need to be
> 64-byte aligned.
