Use the BoundedVec to limit the supported number of refs in
RefAnnouncement messages. The size (235) is the maximum supported by
message wire size.
To reduce the complexity of the changes, BoundedVec is used again
instead of using a new bounded Refs or BTreeMap. This requires
defining new Decode/Encode logic for Ref's element types, and
workarounds for arbitrary instances.

Borrow documentation from Rusts standard library to document BoundedVec's
functions, and add documentation tests where appropriate.
And make it's deref trait return a slice instead of a Vec, which is more
common in rust.

Restrict message size decoding by limiting Message's vector size.
Introduce the BoundedVec type to do this on the type level for
convenience and clarity.
