[docs] Move byte-vector docs to common-dylan.

The common-dylan library is the home for the byte-vector module,
so document it there rather than in the collections library docs.

* source/collections/byte-vector.rst: Move to common-dylan.

* source/collections/index.rst: Remove from TOC, add note about byte-vector
  being re-exported from here.

* source/common-dylan/index.rst: Link in byte-vector docs and remove
  the corresponding TODO item.
