Thomas Köppe 4e582b0c1d [flexbuffers] Add "AlignedBlob", a version of "Blob" with explicit alignment. (#8993)
A blob is an array of bytes and has no intrinsic alignment (i.e. the
alignment is 1). The alignment of the existing flexbuffers blob is
solely affected by the width of the integer needed to store the blob's
size: that integer's width becomes the alignment of the blob.

The proposed AlignedBlob function here piggybacks on this effect and
simply uses a user-defined alignment for the width of the integer that
stores the blob's size; this automatically imparts that same alignment
on the blob itself. (The width is bounded below by the actual width
needed to store the blob's size.)

The ability to control the alignment of a blob is important for use
cases in which the blob itself stores structured data that we want to
access without further copies (e.g. other flatbuffer messages).
